Setup Menu Model 6200T Total Sulfur Analyzer 5.4.1. Available Analog Output Signals The analyzer has three active analog output signals, accessible through a connector on the rear panel.
6200T Total Sulfur Analyzer Setup Menu concentration of SO2 is typically less than 500 ppb, the full scale of expected values is only 0.25% of the instrument’s full 20,000 ppb measurement range. Unmodified, the corresponding output signal would also be recorded across only 0.25% of the range of the recording device.
Setup Menu Model 6200T Total Sulfur Analyzer 5.4.3. Reporting Range Modes: Single, Dual, Auto Ranges The 6200T provides three analog output range modes to choose from: Single range (SNGL) mode sets a single maximum range for the analog output. If single range is selected (refer to Section 5.4.3.1) both outputs are slaved together and will represent the same measurement span (e.g. 0-50 ppm), however their electronic signal levels may be configured for different ranges (e.g. 0-10 VDC vs. 0-.
6200T Total Sulfur Analyzer Setup Menu 5.4.3.1. Single Range mode (SNGL) The default range mode for the analyzer is single range, in which all analog concentration outputs are set to the same reporting range. This reporting range can be set to any value between 0.1 ppb and 20,000 ppb. While the two outputs always have the same reporting range, the span and scaling of their electronic signals may also be configured for different differently (e.g., A1 = 0-10 V; A2 = 0-0.1 V).
Setup Menu Model 6200T Total Sulfur Analyzer 5.4.3.2. Dual Range Mode (DUAL) Selecting Dual Range mode allows the A1 and A2 outputs to be configured with different reporting ranges. The analyzer software calls these two ranges low and high. The Low range setting corresponds with the analog output labeled A1 on the rear panel of the instrument. The high range setting corresponds with the A2 output. While the software names these two ranges low and high, they do not have to be configured that way.
6200T Total Sulfur Analyzer Setup Menu 5.4.3.3. Auto Range Mode (AUTO) In AUTO range mode, the analyzer automatically switches the reporting range between two user-defined ranges (low and high). The unit will switch from low range to high range when either the SO2 concentration exceeds 98% of the low range span. The unit will return from high range back to low range once both the SO2 concentration falls below 75% of the low range span.

Setup Menu Model 6200T Total Sulfur Analyzer 5.9.4. Optic Test The optic test function tests the response of the PMT sensor by turning on an LED located in the cooling block of the PMT (refer to Figure 13-18). The analyzer uses the light emitted from the LED to test its photoelectronic subsystem, including the PMT and the current to voltage converter on the preamplifier board. To ensure that the analyzer measures only the light coming from the LED, the analyzer should be supplied with zero air.
6200T Total Sulfur Analyzer Setup Menu 5.9.5. Electrical Test The electrical test function creates a current, which substitutes the PMT signal, and feeds it into the preamplifier board. This signal is generated by circuitry on the preamplifier board itself and tests the filtering and amplification functions of that assembly along with the A/D converter on the motherboard. It does not test the PMT itself. The electrical test should produce a PMT signal of about 2000 ±1000 mV.
Setup Menu Model 6200T Total Sulfur Analyzer 5.9.6. Lamp Calibration An important factor in accurately determining SO2 concentration is the amount of UV light available to transform the SO2 into SO2* (refer to Section 13.1.1). The 6200T compensates for variations in the intensity of the available UV light by adjusting the SO2 concentration calculation using a ratio (LAMP RATIO)that results from dividing the current UV lamp (UV LAMP) intensity by a value stored in the CPU’s memory (LAMP_CAL).
6200T Total Sulfur Analyzer Setup Menu 5.9.7. Pressure Calibration A sensor at the exit of the sample chamber continuously measures the pressure of the sample gas. This data is used to compensate the final SO2 concentration calculation for changes in atmospheric pressure when the instrument’s TPC feature is turned on (refer to Section 10.7.3) and is stored in the CPU’s memory as the test function PRES (also viewable via the front panel). Ensure to use a barometer that measures actual barometric pressure.
Setup Menu Model 6200T Total Sulfur Analyzer 5.9.8. Flow Calibration The flow calibration allows the user to adjust the values of the sample flow rates as they are displayed on the front panel and reported through COM ports to match the actual flow rate measured at the sample inlet. This does not change the hardware measurement of the flow sensors, only the software calculated values.
6200T Total Sulfur Analyzer Setup Menu 5.9.9. Test Channel Output When activated, output channel A3 can be used in the standard configuration to report one of the test functions viewable from the SAMPLE mode display.

6200T Total Sulfur Analyzer Calibration Procedures 9. CALIBRATION PROCEDURES This section describes the calibration procedures for the 6200T. All of the methods described in this section can be initiated and controlled through the COM ports. IMPORTANT IMPACT ON READINGS OR DATA If you are using the 6200T for US-EPA controlled monitoring, refer to Section 10 for information on the EPA calibration protocol. 9.1.
Calibration Procedures Model 6200T Total Sulfur Analyzer standard charcoal scrubber that supplies zero air for the diluter assembly. The second scrubber is located inside the analyzer behind the sample filter. This scrubber uses a specially impregnated charcoal (TAI Part# CH_52) which is especially effective in scrubbing TS gases. This filter is used to scrub TS from the inlet sample gas for use in zero calibrating the analyzer.
6200T Total Sulfur Analyzer Calibration Procedures 9.1.1.3. Calibration Gas Standards and Traceability All equipment used to produce calibration gases should be verified against standards of the National Institute for Standards and Technology (NIST). To ensure NIST traceability, we recommend acquiring cylinders of working gas that are certified to be traceable to NIST Standard Reference Materials (SRM). These are available from a variety of commercial sources.

6200T Total Sulfur Analyzer Calibration Procedures 9.5. Manual Calibration with IZS Option Under the best conditions, the accuracy off the SO2 effusion rate of the IZS option’s permeation tube is about ±5%. This can be subject to significant amounts of drift as the tube ages and the amount of SO2 contained in the tube is depleted. Whereas this may be sufficient for informal calibration checks, it is not adequate for formal calibrations and is not approved for use by the US EPA as a calibration source.
Calibration Procedures Model 6200T Total Sulfur Analyzer To perform a manual calibration check of an analyzer with a zero/span valve or IZS Option installed, use the following method: STEP ONE: Connect the sources of Zero Air and Span Gas as shown below.

RANGE = 500.000 PPB < TST TST > CAL CALZ CALS SAMPLE Wait until STABIL falls below 0.5 ppb. This may take several minutes. STABIL=XXX.X PPB < TST TST > CAL CALZ CALS ZERO CAL M STABIL=XXX.X PPB < TST TST > ZERO SAMPLE The value of STABIL may jump significantly. Wait until STABIL falls below 0.5 ppb. This may take several minutes. CONC STABIL=XXX.
Calibration Procedures Model 6200T Total Sulfur Analyzer 9.7. Manual Calibration in DUAL or AUTO Reporting Range Modes When the analyzer is in either Dual or Auto Range modes the user must run a separate calibration procedure for each range. After pressing the CAL, CALZ or CALS buttons the user is prompted for the range that is to be calibrated as seen in the CALZ example below: SAMPLE RANGE = 500.000 PPB SO2 =XXX.
6200T Total Sulfur Analyzer Calibration Procedures calibrate the analyzer until the contact is opened. At this point, the new calibration values will be recorded before the instrument returns to SAMPLE mode. If the AutoCal attribute CALIBRATE is disabled, the instrument will return to SAMPLE mode, leaving the instrument’s internal calibration variables unchanged. 9.8.
Calibration Procedures Note Model 6200T Total Sulfur Analyzer The CALIBRATE attribute must always be set to OFF for analyzers used in US EPA controlled applications that have IZS option installed. Calibration of instruments used in US EPA related applications should only be performed using external sources of zero air and span gas with an accuracy traceable to EPA or NIST standards and supplied through the analyzer’s sample port (refer to Section 9.2).

6200T Total Sulfur Analyzer Principles of Operation 13. PRINCIPLES OF OPERATION This section describes the principles of operation for the 6200T SO2 analyzer (Section 13.1), for the optional O2 sensor (Section 13.2) and for the optional CO2 sensor (Section 13.3). It also describes the principles of operation for pneumatics (Section 13.4), electronics (Section 13.5), communication interfaces (13.6) and software (13.7). 13.1.
Principles of Operation Model 6200T Total Sulfur Analyzer The amount SO2 converted to excited SO2* in the sample chamber is dependent on the average intensity of the UV light (Ia) and not its peak intensity because the intensity of UV light is not constant in every part of the sample chamber. Some of the photons are absorbed by the SO2 as the light travels through the sample gas.
6200T Total Sulfur Analyzer Principles of Operation The amount of detectable UV given off by the decay of the SO2* is affected the rate at which this reaction occurs (k). F k SO2 * (Equation 13-4) Where: F = the amount of fluorescent light given off. k = The rate at which the SO2* decays into SO2. SO2* = Amount of excited SO2 in the sample chamber. Therefore: F k SO2 * SO2 hv330nm (Equation 13-5) Finally, the function (k) is affected by the temperature of the gas.
Principles of Operation Model 6200T Total Sulfur Analyzer The net result is that any variation in UV fluorescence can be directly attributed to changes in the concentration of SO2 in the sample gas. 13.1.2. The UV Light Path The optical design of the 6200T’s sample chamber optimizes the fluorescent reaction between SO2 and UV Light (refer to Figure 13-2) and assure that only UV light resulting from the decay of SO2* into SO2 is sensed by the instruments fluorescence detector.
6200T Total Sulfur Analyzer Principles of Operation Figure 13-2: UV Light Path 13.1.3. UV Source Lamp The source of excitation UV light for the 6200T is a low pressure zinc-vapor lamp. An AC voltage heats up and vaporizes zinc contained in the lamp element creating a lightproducing plasma arc. Zinc-vapor lamps are preferred over the more common mercuryvapor lamps for this application because they produce very strong emission levels at the wavelength required to convert SO2 to SO2*, 213.
Principles of Operation Model 6200T Total Sulfur Analyzer A PMT is typically a vacuum tube containing a variety of specially designed electrodes. Photons enter the PMT and strike a negatively charged photo cathode causing it to emit electrons. These electrons are accelerated by a high voltage applied across a series of special electrodes called dynodes that multiply the amount of electrons until a useable current signal is generated.

Principles of Operation Model 6200T Total Sulfur Analyzer 13.4.2. Flow Rate Control The 6200T uses a special flow control assembly located in the exhaust vacuum manifold (refer to Figure 13-10) to maintain a constant flow rate of the sample gas through the instrument. This assembly consists of: A critical flow orifice. Two o-rings: Located just before and after the critical flow orifice, the orings seal the gap between the walls of assembly housing and the critical flow orifice.
6200T Total Sulfur Analyzer Principles of Operation The actual flow rate of gas through the orifice (volume of gas per unit of time), depends on the size and shape of the aperture in the orifice. The larger the hole, the more gas molecules, moving at the speed of sound, pass through the orifice.

6200T Total Sulfur Analyzer ESD Primer charges from building up on the device or assembly and nearby static fields from discharging through it. Use metallic anti-ESD bags for storing and shipping ESD sensitive components and assemblies rather than pink-poly bags.
ESD Primer Model 6200T Total Sulfur Analyzer 3. Open the casing of the analyzer and begin work. Up to this point, the closed metal casing of your analyzer has isolated the components and assemblies inside from any conducted or induced static charges. 4. If you must remove a component from the instrument, do not lay it down on a nonESD preventative surface where static charges may lie in wait. 5. Only disconnect your wrist strap after you have finished work and closed the case of the analyzer. 14.5.2.
6200T Total Sulfur Analyzer ESD Primer If you are at an anti-ESD workbench, lay the container down on the conductive work surface while your wrist strap is connected to a ground point. In either case wait several seconds. 4. Place the item in the container. 5. Seal the container. If using a bag, fold the end over and fasten it with anti-ESD tape. Folding the open end over isolates the component(s) inside from the effects of static fields.
