SS500e/SS2000e/SS3000e Gas Analyzer SpectraSensors Overview SpectraSensors, Inc. is a leading manufacturer of advanced electro-optic gas analyzers. Headquartered in Houston, Texas, SpectraSensors was incorpo- rated in 1999 as a spin-off of the NASA/Caltech Jet Propulsion Laboratory (JPL) for the purpose of commercializing space-proven measurement technol- ogies initially developed at JPL.
Introduction How the Analyzers Work The SS500e/SS2000e/SS3000e analyzers employ tunable diode laser absorption spectroscopy (TDLAS) to detect the presence of trace substances in process gases. Absorption spectroscopy is a widely used technique for sensitive trace species detection. Because the measurement is made in the volume of the gas, the response is much faster, more accurate and significantly more reliable than traditional surface-based sensors that are subject to surface contamination.
SS500e/SS2000e/SS3000e Gas Analyzer by the detector at the end of the beam path of length I (cell length x number of passes), is given by I exp lN – where N represents the species concentration. Thus, the ratio of the absorption measured when the laser is tuned on-resonance versus off-resonance is directly proportional to the number of molecules of that particular species in the beam path, or...
Introduction 0.99 0.98 0.97 0.96 Normalized Absorption Signal 0.95 Wavelength [a.u.] Figure 1–3 Typical normalized absorption signal from a laser diode absorption spectrometer Note that contamination of the mirrors results solely in lower overall signal. However, by tuning the laser off-resonance as well as on-resonance and normalizing the data, the technique self calibrates every scan resulting in measurements that are unaffected by mirror contamination.
SS500e/SS2000e/SS3000e Gas Analyzer Normalized 2f Signal Wavelength [a.u.] Figure 1–4 Typical normalized 2 signal; species concentration is proportional to the peak height With the resulting low-noise signal and use of fast post-processing algorithms, reliable parts per million (ppm) or parts per billion (ppb) detection levels are possible (depending on target and background species) at real-time response rates (on the order of 1 second).

4 - S AMPLE ONDITIONING YSTEM Personnel should have a thorough understanding of the operation of the analyzer and the procedures presented here before operating the sample conditioning system (SCS). The process sample at the sample tap may be at a high pressure. A pressure reducing regulator is located at the sample tap to reduce the sample pressure and allow operation of the sample conditioning system at a low pressure.
SS500e/SS2000e/SS3000e Gas Analyzer Typical SCS Component Overview All SpectraSensors TDL analyzers are designed for extractive sampling rather than in situ applications. This allows for sample conditioning, filtration, temperature, pressure and flow control to protect the optical components of the system, and provides for ease of maintenance without shutting down the process.
Sample Conditioning System Heated Enclosure Heated Enclosure Analyzer Heat Trace Regulator Probe Figure 4–1 Probe to analyzer interface Sample conditioning system filters The sample system is equipped with a membrane separator, which is ideal for the removal of relatively small amounts of liquid present on a continuous basis (i.e., aerosols and suspended liquids).
SS500e/SS2000e/SS3000e Gas Analyzer some sample components. Sample probe regulators can be electrically or steam heated. Some probes have the pressure reducing valve parts inserted into the process piping, so that the Joule-Thompson cooling is offset by warming from the flowing sample. Note that for these probes to work correctly, the process gas must be flowing anytime the sample is flowing or liquid condensation may collect in the sample transport line, or even freeze up the sample probe regulator.
Sample Conditioning System Sample return/vent Tunable diode laser spectroscopy is inherently sensitive to sample pressure in the measurement cell, so the analyzers are calibrated for a range of sample pressures. Most applications benefit from operation at low pressures instead of high pressures.
SS500e/SS2000e/SS3000e Gas Analyzer 3. Confirm that the relief valve vent line is properly installed from the field pressure reducing station or the SCS to the low pressure flare or atmospheric vent connection. 4. If applicable, confirm that the sample probe and field pressure reducing station are properly traced and insulated without any exposed surfaces.
Sample Conditioning System 5. Confirm that the pressure regulator at the field pressure reducing station is closed (adjustment knob turned fully counterclockwise). 6. Confirm that all sample system shut-off valves are closed. 7. Confirm that the sample bypass and analyzer flowmeter control valves are gently closed (adjustment knob turned clockwise).
SS500e/SS2000e/SS3000e Gas Analyzer 2. Open the sample supply shut-off valve. 3. Open the bypass flowmeter control valve to establish sample flow from the sample probe and set the flowmeter control valve to the specified value. Refer to the system drawings in Appendix A. Do not open the cell flowmeter at this point.
Sample Conditioning System The adjustment setpoints of the analyzer flowmeters and pressure regulators will be iterative and may require multiple adjustments until the final setpoints are obtained. The analyzer system has been designed for the sample flow rate specified. A lower than specified sample flow rate may adversely affect analyzer performance.
SS500e/SS2000e/SS3000e Gas Analyzer To isolate the measurement sample cell for short‐term shutdown The analyzer can be isolated from the primary sample bypass section for short- term shutdown or maintenance of the analyzer while allowing the sample bypass flow to continue in a steady-state mode. Due to the high pressure of the process sample, it is advisable to allow the sample bypass flow to continue during short-term isolation of the analyzer.
Sample Conditioning System Although the pressure reducing regulator at the process sample tap is designed for “bubble-tight” shut off, this condition may not occur after the system has been in operation for an extended period. Isolation of the SCS from the field pressure regulator will discontinue sample flow and may cause the pressure at the outlet of the field pressure regulator to slowly increase if “bubble-tight”...
Page 62
SS500e/SS2000e/SS3000e Gas Analyzer All valves, regulators, switches, etc. should be operated in accordance with site lock-out/tag-out procedures. 1. Isolate the analyzer from the bypass following the procedure under “To isolate the measurement sample cell for short-term shutdown” on page 4-10. 2.
