Determinator Power On/Off Switch—Switches power on and off to the determinator. Also acts as a circuit breaker on the incoming facility line power. Measure Flow Rotameter—Indicates the oxygen flow rate in lpm (liters per minute). Nominal indication is 3.0 lpm. Keypad—The keypad is used as a communications link between the operator and the determinator. Operation of the determinator is controlled from the keypad. Display Screen—The display screen provides a visual link between the operator and determinator. Brightness—The brightness control, on top of unit, adjusts the brightness of the display screen. This control should be adjusted by the operator for the amount of brightness desired. Contrast—The contrast control, on top of unit, adjusts the contrast of the display screen. This control should be adjusted by the operator for the best display contrast and is usually adjusted after the brightness control has been properly set. Printer (not shown)—The printer is used to print out analysis data, information presented on the display, and buffer or screen plots. Furnace Power On/Off Switch—Switches power on and off to the furnace. Also acts as a circuit breaker on the incoming facility line power. Power Lever Adjustment—Controls oscillator maximum power output by adjusting the plate current for approximately 100 mA (idling current) to 500 mA (full power). The overload protection is reset by turning the adjustment fully counterclockwise until it clicks and then turning it clockwise. Vacuum Cleaner On/Off Switch—Turns the optional vacuum cleaner on or off. The vacuum cleaner can be used to clear dust and debris from the combustion area and furnace shelf. Piston Up/Down Switch—This switch controls the movement of the piston, either up or down. During operation, the piston raises the crucible and sample into the furnace for analysis. This switch is also used to control the piston during furnace cleaning.

Operation Guidelines Listed below are guidelines that should be followed before analysis, after analysis and after use. By using this information, along with the procedures in the Operation Chapter, the operator will be able to obtain the best possible performance from this instrument.

Note

5–6

•

Do not turn the AC power off to the instrument unless it malfunctions or it's not going to be used for an extended period of time.

•

If the gas is turned off for eight hours or more, do not perform an analysis until the gas has been turned on for at least one hour.

•

The piston should be left up with the crucible removed when the furnace is not in use.

•

Refer to Before Analysis for before analysis guidelines.

•

Refer to After Analysis for after analysis guidelines.

•

Refer to After Use for after use guidelines.

CS-200

Operation

Before an Analysis Before a sample can be analyzed and an accurate result obtained, the instrument must be prepared for analysis. This includes inspecting and cleaning the combustion system orings, performing a system leak check, selecting or creating a method, performing a blank calibration and then performing a standard calibration. Note

•

1.

This procedure prepares the instrument for analysis, not the sample. Refer to Sample Preparation on page 5–10 for sample preparation procedures. Perform daily maintenance before the start of analysis. A.

Inspect and grease the Combustion O-rings. Refer to Combustion Zone O-rings, page 6–16.

B.

Clean the Autocleaner and Mesh Filter. Refer to Autocleaner, page 6–6.

C.

Perform a Leak Check. Refer to page 8–10.

2.

Verify that the gas is turned on.

3.

Verify that the oven is on and reached the proper temperature. Refer to Ambient Monitor, page 8–5.

4.

Select or create a Method to use for analysis. Reference application notes to determine the method parameter values to enter. Refer to Method Development page 4–53.

5.

Analyze 3 to 5 blank conditioning samples. This will purge the system before analysis.

6.

Analyze 3 to 5 blanks and perform a Blank Calibration. This will set the blank calibration value. Refer to Blank Calibration page 5–75.

7.

Analyze a Blank Check Sample to determine if the blank value was set properly. Refer to Login a Sample page 5– 63.

8.

Perform a Drift Correction and analyze 3 to 5 standard samples. This will set the drift correction value. Refer to Drift Correction page 5–79.

9.

Analyze a Standard Check Sample to determine if the drift value was set properly. Refer to Drift Correction page 5– 79.

10. At this point the instrument is ready for Sample Analysis. Refer to Analyze a Sample on page 5–68.

Operation

CS-200

5–7

After an Analysis When an analysis is complete, the furnace automatically shuts OFF, a signal sounds, and the spreadsheet shows the final result. If Line Printing and Automatically Print After Each Analysis is selected, the printer will print the analysis result. Refer to Configure the Analysis Report, page 4–48.

After Use The AC power to the instrument should remain on at all times. If the power to the instrument is switched off for any reason a one-hour warm-up is necessary before analyzing samples. The instrument automatically switches to conservation (low gas flow) after an amount of time specified by the Conservation Time-out in System Configuration, page 4–59. Remove the crucible from the furnace after use.

Note

5–8

•

The furnace should be closed except when loading and unloading samples or when maintenance is being performed. If the furnace is left open for an extended period of time, analyze 3 to 5 conditioner samples before resuming normal operation.

Calibration Calibration is the process that adjusts the instrument to produce an analysis result to equal that of a known calibration standard with the same concentration. First a Blank Calibration is performed, then Standard Calibration and then as daily maintenance both a Blank Calibration and Drift Correction. Single point calibration calibrates the instrument to one calibration point. Multi-point calibration calibrates the instrument to a set of calibration points over an expected range of concentrations.

Blank Calibration Blank Calibration is used to calculate the system blank or baseline. Sometimes this is called the blank area. Blank calibration calculates the system blank and compensates for it when calculating the analysis result. The system blank should be determined every day by performing a blank calibration before analysis. Refer to Blank Calibration on page 5–75.

Standard Calibration Standard Calibration is used to calibrate the instrument with known calibration standards. A single point or multi-point calibration can be performed and the curve type selected although, LECO recommends multipoint, linear calibrations that employ 1/certified weighting. Additionally a blank calibration should be completed prior to performing a standard calibration. Since Standard Calibration is saved with each method, each method must be calibrated after it is created. Refer to Standard Calibration on page 5–76.

Drift Correction Drift Correction is used to compensate standard calibration and account for variances in the instrument hardware that can slightly change the calibration. Drift correction should be performed at the start of every day. This insures accurate calibration and analysis results. Refer to Drift Correction on page 5–79.

CS-200

Theory of Operation

General Information The CS-200 Carbon/Sulfur Determinator is a microprocessor based, software driven instrument for measurement of carbon and sulfur content in metals, ores, ceramics, and other inorganic materials. The CS-200 uses an induction furnace and measures carbon and sulfur by infrared absorption. Analysis begins by weighing out a sample (1 g nominal) into a ceramic crucible on a balance. Accelerator material is added, the crucible is placed on the loading pedestal, and the analyze key is pressed. Furnace closure is performed automatically, then the combustion chamber is purged with oxygen to drive off residual atmospheric gases. After purging, oxygen flow through the system is restored and the induction furnace is turned on. The inductive elements of the sample and accelerator couple with the high frequency field of the furnace. The pure oxygen environment and the heat generated by this coupling cause the sample to combust. During combustion, carbon bearing elements are reduced, releasing the carbon, which immediately binds with the oxygen to form CO and CO2, the majority being CO2. Also, sulfur-bearing elements are reduced, releasing sulfur, which binds with oxygen to form SO2. Sample gases are swept into the carrier stream. Sulfur is measured as sulfur dioxide in the first IR cell. A small amount of carbon monoxide is converted to carbon dioxide in the catalytic heater assembly; SO2 is converted to SO3, while sulfur trioxide is removed from the system in a cellulose filter. Carbon is measured as carbon dioxide in the IR cell as gases flow through the IR cells. The optional automatic autocleaner is ideal for high volume applications and reduces operator time. The autocleaner brushes the filter screen and combustion tube at intervals specified in System Configuration.

Theory of Operation

CS-200

7–3

Infrared Radiation, Absorption, and Detection The infrared (IR) source consists of nichrome wire that is resistance-heated to 850oC. The IR source radiates visible energy as well as all wavelengths in the infrared spectrum. The description below uses carbon dioxide although, the same principle applies to sulfur detection. Carbon dioxide absorbs IR energy at a precise wavelength within the IR spectrum. Energy from the IR source is absorbed as the gas passes through the cell, preventing it from reaching the IR detector. All other IR energy is prevented from reaching the IR detector by a narrow bandpass filter. Because of the filter, the absorption of IR energy can be attributed only to carbon dioxide (CO2). The concentration of CO2 is detected as a reduction in the level of energy at the detector. One IR cell is used as both a reference and for measurement. The total carbon, as carbon dioxide, is detected on a continuous and simultaneous basis. The cell consists of an IR source, chopper motor, a narrow bandpass filter, a condensing cone, an IR energy detector and the cell body. Radiated energy is chopped at a rate of 87.5 Hz. before it enters the cell body. The chopped energy enters the cell body through a window, travels through the cell body, then exits through a second window and a precise bandpass filter. The selective filter passes only the CO2 absorption wavelength into a condensing cone that concentrates the energy on the detector. The solid state detector is AC coupled to a preamplifier. As the gas concentration increases, the voltage to the preamplifier decreases. The starting reference level, or baseline, for the detector is established by running 100% oxygen through the cell. The pure oxygen environment permits the maximum amount of energy to reach the detector. This maximum energy level is AC coupled to the preamp where it is amplified, rectified, and filtered. It is then sent to an A/D converter where the analog signal is converted to a digital signal. The nominal voltage read at the cell output, via the Ambient Monitor, is 8.500 VDC. During every analysis, the computer reads the baseline. This level is then adjusted digitally until a nominal level is achieved. For example, if the cell output is 8.400 VDC, then this level is change digitally until the level reads 8.500 VDC. This level change is done in the computer and used for a reference, if the cell output voltage were actually measured, no change would be observed.

7–4

CS-200

Theory of Operation

As analysis begins, the cell output decreases with the amount of carbon (as CO2) present in the cell. The computer reads the cell output 20 times per second and produces data points that are stored in memory. The computer then processes the curve or graph formed by these data points. The curve or graph is then used by the computer to calculate the element weight percent of an unknown sample.

Comparator Level

Note

•

One comparator level is associated with each analysis method. Selecting a different method also selects a new comparator level.

An analysis that lasts excessively long causes unnecessarily long delays, while an analysis that isn’t long enough can cause loss of significant analyte data collection. Since not all samples combust in the same manner, analyses should not be performed based on time alone. The length of each analysis is determined on an individual basis by the minimum analysis time and the comparator level. Analysis ends when the minimum time limit is reached and the analyte rate drops below the comparator level after passing its peak. This comparator level is a preset constant (k) plus a percent of the peak: COMPARATOR LEVEL = k + (X)(P) P

Detector output peak

X

Selected comparator level percentage

During an analysis, the output of the detector is collected in the form of digital data and summed to arrive at the analysis result. If this data were plotted, it would reflect the curve of the detector output.

7–8

CS-200

Theory of Operation

Shown below are two examples of the same detector output curve (buffer plot). The first example shows the amount of detector output collected during an analysis with a comparator level setting at 6% while the second example illustrates at 25%.

The following conclusions can be drawn from the examples: 1.

A high comparator level shortens analysis time.

2.

A low comparator level includes more sample gas, and therefore more sulfur, into result calculations.

3.

A comparator level that is too low, however, results in the inclusion of very low concentrations that don’t significantly effect the result (noise), but lengthen the analysis.

A comparator level of 1.0% usually provides optimum performance by allowing the collection of all significant output within a reasonable time.

Theory of Operation

CS-200

7–9

Extremely low output peaks may need a larger comparator level to exclude insignificant output levels produced toward the end of analysis and cut down on drift. The minimum time should be extended to match what would be considered a reasonable time length for the analysis of such samples. The combination of a high comparator level and an extended minimum analysis time insures that all significant output is collected and analysis time lengths are consistent without being extensive. Whenever the comparator level changes check the system calibration since interaction can occur. COMPARATOR LEVEL (SET TOO HIGH)

Leak Check This procedure automatically check the measurement system of the instrument for a gas leak. The entire system can be checked or the operator can by-pass the furnace to isolate the leak. During a system leak check the system is pressured to 500 mm Hg above current system pressure and sealed. It is then permitted to equilibrate. For the next 60 seconds the system pressure is measured. If the pressure remains within 5 mm Hg of the pressurized value the system passes the leak check (for system check only). If the pressure changes more than 5 mm Hg of the pressurized value the leak check fails. In the Leak Check Progress box the status of the leak check is displayed. If a leak check fails it may be caused by gas leaking into or out of the system. If “Change in Pressure” has increased the incoming valve SV6 may be malfunctioning or the catalyst heater tubes are not at a steady temperature. If “Change in Pressure” has decreased gas is leaking out of the system. If a leak is present, "Leak Check Failed" appears next to “Leak Check Status”. If there isn't a leak " Leak Check Passed" appears. If the system fails a leak check and a leak is detected, perform a “by-pass the furnace” leak check to isolate the leak. Before a leak check is performed the instrument should warm up for at least for 30 minutes and the catalyst heater tubes must be at a steady temperature. It is recommended that a leak check be performed after autocleaner maintenance, furnace maintenance or anytime a reagent tube is removed or replaced.

Barometric (PID) Pressure Regulator Adjustment This adjustment has been factory set to a highest anticipated barometric pressure of 762 mm. If the highest anticipated pressure in the operational environment varies more than ±5 mm from 762 mm, this adjustment must be performed to eliminate calibration shifts that may occur as a result of barometric pressure changes. The present (operation environment) barometric pressure must be determined. If an accurate method of measurement is not available, the nearest weather bureau or airport can provide this information. The pressure must be referenced to the operational site altitude, not sea level. The highest anticipated pressure for the area must also be determined.

Notes

•

The determinator power must be on for a minimum of 30 minutes prior to performing this adjustment.

•

The furnace piston must be in the up position and the furnace power switch must be in the on position.

Turn off the service switch and verify that the plate and grid currents go to zero.

4.

Turn the power level control clockwise to the max position.

5.

Put a calibration load on the furnace pedestal.

•

If the calibration load recommended and calibrated by LECO is not used during adjustment, the performance of this instrument cannot be guaranteed.

6.

Press the piston switch on the furnace. The pedestal should rise.

9.

Verify that turning power level control up and down (located on the front panel) causes the plate current to increase and decrease respectively. Return the power level control to the max position.

If the power level control adjustments do not seem to affect the power level read-out, adjust R29 down and try adjusting the power level control again. Adjust the overload control (R32) up (approximately 10 turns) to prevent the furnace from going into overload.

10. Adjust the offset control (R29) as follows:

Note

•

A.

If the oscillator current is below 500 mA, adjust R29 counterclockwise until 500 mA of plate current is obtained and then proceed to step 11.

B.

If the oscillator is not oscillating, and the plate current is low, turn R29 clockwise until 500 mA of plate current is obtained.

C.

With the power control at maximum, adjust R32 counterclockwise until the current overloads. Then gradually adjust R32 clockwise and R29 counterclockwise until the oscillator tube oscillates at 500 mA.

Sometimes it requires a couple of attempts at this step if the oscillator gets into this mode of oscillation. Once the oscillator is set, it should function normally for the life of the oscillator tube.

11. Adjust the overload control, R32, down until the furnace power trips. Be sure the power has actually tripped and that the power has not merely turned off because the analysis has ended. Verification can be accomplished by observing that LED1 is lighted. 12. Turn the overload control back approximately 11/2 turns to ensure that the furnace will go into overload just above the full-scale current setting of 500mA. 13. Reset the overload by turning the power level control to reset and then back to max. Now the furnace should not go into overload when the power level control is returned to max.

Gas Flows

Analysis Analyze Valve State—In this valve state, oxygen flows through both the furnace and the determinator system. When the gas is turned on, oxygen, regulated at 35 psi at its source, enters the determinator through the O2 inlet port on the cabinet back panel. Oxygen flow is then filtered through a 6 inch bubble tube (located on the front of the furnace) containing Lecosorb and anhydrone. Carbon dioxide is removed from the oxygen flow using Lecosorb reagent and moisture is removed in the anhydrone reagent. Oxygen, with all impurities removed, serves as the carrier gas in the system. After all impurities have been removed from the carrier gas, the flow is divided into two paths; one path, the lance flow, is directed through solenoid valve 3 and into the top of the combustion tube. During an analysis, lance flow is held constant and is directed into the sample to assist carbonbearing components to convert into CO or CO2. The second path is directed through solenoid valve 5 into the bottom of the combustion tube; this flow rate varies (2 to 3 lpm) in accordance with each valve state. The carrier gas flows from the combustion tube sweeping released gases from the combustion tube through a screen filter, then through a 4 inch filter tube containing anhydrone to remove water. The carrier gas, regulated by a flow controller in the oven, flows through the catalyst heater. A small percentage of the carbon is present as carbon monoxide, which is converted to carbon dioxide as the gas flows through the platinized silica gel in the heater. Sulfur trioxide is removed in a cellulose trap. Gas then flows through the cellulose trap, CO2 IR cell and solenoid valve 15. It is then exhausted out the back of the unit. Furnace Open 1 Valve State—In this valve state, the combustion tube is depressurized so that residual dust can be ejected. Lance flow remains the same as in the analyze valve state, but the measure flow is bypassed through both solenoid valve 9 and solenoid valve 2. Flow through solenoid valve 9 is briefly purged through the combustion chamber while flow from solenoid valve 2 passes through the cellulose trap and IR cell as previously described for the measure flow. Pneumatic gas flows through the safety pressure regulator. With solenoid valve 9 open, the lance and purge flow (through solenoid valve 9) ejects residual dust from the combustion tube.

10–12

Service

Furnace Open 2 Valve State—In this valve state, the piston moves down and, if selected, the vacuum turns on. Lance flow is on while measure flow bypasses the furnace altogether and flows directly through solenoid valve 2 and is directed to the IR cell. Pneumatic gas is switched through the safety pressure regulator and solenoid valve 10 causing the piston to be lowered. In addition, the vacuum solid-state relay switches on if it has been selected. Furnace Open 3 Valve State—In this valve state, the vacuum, if selected, shuts off and the furnace remains open to load the next crucible on the pedestal. Flow is identical to Furnace Open 2 Valve State, but the vacuum solid state relay switches the vacuum cleaner off. Furnace Closed 1 Valve State—This valve state is triggered when a loaded crucible is placed on the piston and the piston up/down key is pressed. The piston moves up under low pressure until the up piston limit switch closes. Oxygen flow completely bypasses the furnace through solenoid valve 2 and is directed through the cellulose trap and IR cell. Pneumatic gas flows through the safety pressure regulator and closes solenoid valve 10 to move the piston up. Furnace Closed 2 Valve State—In this valve state, the lower seal changes to high pressure and is sealed against the combustion tube o-ring. Atmospheric gases are quickly purged out of the combustion tube. Lance flow is on and measure flow is on through the IR cell as well as purged through the top of the combustion tube. Pneumatic gas allows atmospheric gases to be purged from the combustion tube. Furnace Closed 3 Valve State—After a pre-analyze purge delay, the combustion tube is pressurized in this valve state. Oxygen flow is identical to that in Furnace Closed 2 Valve State, but pneumatic flow goes through solenoid valve 9 only. Analysis Valve State—Following Furnace Closed 3 Valve State, there is a 2 second delay, after which the CPU checks that the lance pressure switch is closed and a weight has been entered in the weight stack. If both conditions are affirmative, the system goes into Analyze Valve State, (previously discussed). During a preanalyze delay, a stable IR baseline is obtained, after which IR zeros are taken. Integration begins just before the furnace is heated. As the sample is combusted in the furnace, sample gases are mixed with the carrier gas (oxygen) and CO2 is collected and released by the trap. Then the gas is directed to the IR cell. Percent carbon is displayed on screen, the furnace shuts off, and the answers are saved in memory and then printed.

Service

CS-200

10–13

Post-Analyze Valve State—In this valve state, lance flow is shut off while measure flow remains on to maintain a constant flow through the IR detection system. Lance flow is off, while measure flow is directed into the bottom of the furnace and subsequently through the IR cell. The piston remains raised under pneumatic pressure.

Autocleaner After a programmed number of analyses, the furnace must be cleaned, either manually or automatically, to prevent excessive residue buildup. The following procedure generally describes both manual and automatic cleaning cycle flows; however, in system controls, several autoclean options can be selected. Refer to the System Controls procedure on page 5–16 and System Configuration on page 4–59, for details. In each of the three clean valve states, oxygen flow is bypassed through the IR cell, the piston is down, and the door is closed. Differences in these valve states include vacuum cleaner on or off and brush up or down. A clean cycle is begun by pressing [5] Clean from the analyze menu. If the cup is up, the combustion tube is depressurized (Furnace Open 1 Valve State) and the lance pressure switch opens. If the piston switch is down, Clean 1 Valve State is signaled and the furnace door closes. If an autocleaner has been installed, the vacuum turns on, the brush moves down (Clean 2 Valve State) and up (Clean 1 Valve State), and then the cycle repeats 2 times. If manually cleaning, the vacuum switch shuts off automatically (Clean 3 Valve State) and the vacuum switch is pressed manually to begin cleaning. After cleaning the filter and combustion tube, the vacuum switch is shut off manually. Then [5] Clean is pressed and the furnace door opens (Furnace Open 3 Valve State). The cycle is completed when atmospheric gases are purged from the system (gas flows for each valve state have been previously discussed). After cleaning, the vacuum is shut off (Furnace Open 3 Valve State), the clean switch is pressed, and the cup moves up under low pressure (Furnace Closed 1 Valve State). The cup then goes to high pressure, sealing the piston against the o-ring. Atmospheric gases are purged from the combustion tube (Furnace Closed 2 Valve State) and after a purge delay, the combustion tube is pressurized. Finally, after a two second delay, oxygen flows through both the furnace and determinator (Post Analyze Valve State).

Software Upgrade A major portion of the determinator's functions are defined and controlled by a software program that may be updated. Most updates do not affect the physical design of the determinator, but can improve performance and make operation easier. Therefore, an identification system for program changes called 'Program Version' is used in the CS-200 Carbon and Sulfur Determinator and other LECO instruments. A three-digit number identifies program version levels. The first generation of a program is version '1.00'. Each time a program is changed, the version number is increased.

•

The following information is for Windows® instruments. For DSP instruments refer to Linearization on page 10–30.

The output signal (voltage) from the IR cell detector is not linear with respect to element concentration. To make the output of the IR cell appear linear, each cell is linearized by LECO during the manufacturing process. Notes

•

It is only necessary to perform this procedure if an IR cell is replaced. The reference and saturation values to enter during this procedure can be found on a tag attached to the replacement IR cell.

•

The Break and Slope values are not used by LECO but can be used by the operator to customize their instrument. Click on the table to enter a break and slope value.
