1 - I NTRODUCTION SpectraSensors’ SS2100r products are high-speed, diode-laser based extractive analyzers designed for extremely reliable monitoring of very low (trace) to standard concentrations of specific components in various background gases. In order to ensure that the analyzer performs as specified, it is important to closely review the installation and operation sections of this manual.
SS2100r H S Analyzer Failure to follow all directions may result in damage or malfunction of the analyzer. General notes and important information concerning the installation and operation of the analyzer. Failure to follow all directions may result in fire. Maximum voltage and current specifications for fuses.
Introduction controlled by microprocessor-based electronics with embedded software that incorporates advanced operational and data processing algorithms. Sample Conditioning System Sample conditioning is included in the system and has been specifically designed to deliver an optimum sample stream that is representative of the process systems stream at the time of sampling.

SS2100r H S Analyzer Differential TDLAS Similar to TDLAS, this SpectraSensors technology involves subtracting two spectrums from one another. A “dry” spectrum, a response from the sample when the analyte of interest has been completely removed, is subtracted from the “wet” spectrum, a response from the sample when the analyte is present. The remainder is a spectrum of the pure analyte.
Introduction All SpectraSensors TDL gas analyzers employ the same design and hardware platform. Measuring different trace gases in various mixed hydrocarbon background streams is accomplished by selecting a different optimum diode laser wavelength between 700-3000 nm, which provides the least amount of sensitivity to background stream variations.
Introduction Analyzer electronics assembly Figure 1–8 shows the analyzer electronics assembly. The analyzer power supply provides power to the analyzer control electronics. The analyzer control electronics drive the laser, collect the signal and analyze the spectra. A DIN rail holds fused terminal blocks, the temperature controller and solid-state relay for the heater, powered relays controlling the solenoid valves and un-powered relays serving as alarm contacts.

SS2100r H S Analyzer Never lift the analyzer by the exposed components as damage to the analyzer could occur. Mounting the analyzer The SS2100r analyzer is manufactured for indoor 19" rack installations. The overall analyzer weight necessitates the use of a support shelf. A heavy-duty sliding shelf, like the one shown in Figure 2–1, capable of supporting 3.5 times the weight of the analyzer is required.
Installation Hazardous voltage and risk of electric shock. Failure to properly ground the analyzer may create a high-voltage shock hazard. To connect electrical power to the analyzer: 1. Access the back panel of the enclosure. 2. Confirm that the power switch is turned off. 3.

Appendix B: Troubleshooting & Maintenance This section presents recommendations and solutions to common problems, such as gas leaks, contamination, excessive sampling gas temperatures and pressures, and electrical noise. If your analyzer does not appear to be hampered by one of these related problems, contact SpectraSensors service department.
SS2100r H S Analyzer Exposure to process gases 1. Shut off the process gas to the analyzer before any service that would require opening a part of the sample plumbing. 2. Purge the system with nitrogen. 3. Shut off the nitrogen purge before opening any part of the sample system.
Troubleshooting & Maintenance appropriate for the area and hazards present. Electrical connections must not be made or broken with power on (to avoid arcing). Gas Leaks Probably the most common cause of erroneous measurements is outside air leaking into the sample supply line. SpectraSensors recommends periodically leak-testing the supply lines, especially if the analyzer has been relocated or has been replaced or returned to the factory for service and the supply lines have been reconnected.
SS2100r H S Analyzer 5. Wash the sampling line with isopropyl alcohol or acetone and blow dry with mild pressure from a dry air or nitrogen source. 6. Once the sampling line is completely free of solvent, reconnect the gas sampling line to the sample supply port of the analyzer. 7.
Troubleshooting & Maintenance The sample cell assembly contains a low-power, 20 mW MAX, CW Class 3b invisible laser with a wavelength between 800-3000 nm. Never open the sample cell flanges or the optical assembly unless the power is turned off. Tools and Supplies: •...

Personnel should have a thorough knowledge and understanding of the physical properties and safety precautions for the sample contents before operating the SCS.
Troubleshooting & Maintenance 10. Place a few drops of isopropyl alcohol onto the mirror and rotate the mirror to spread the liquid evenly across the mirror surface. Isopropyl alcohol can be hazardous. Follow all safety precautions when in use and thoroughly wash hands prior to eating. 11.
