  • Page 13: Who Should Read This Manual

    Take a moment to familiarize yourself with this Operator’s Manual by reading the Table of Contents. There are a number of options and accessories available for the SS1000 analyzers. This manual has been written to address the most common options and accessories.
  • Page 14: Special Symbols Used In This Manual

    SS1000 Operator’s Manual Special Symbols Used in This Manual This manual uses the following symbols to represent potential hazards, caution alerts, and important information associated with the analyzer. Every symbol has significant meaning that should be heeded. This icon denotes a warning statement. Warning statements indicate a potentially hazardous situation which, if not avoided, may result in serious injury or death.

  • Page 16: Spectrasensors Overview

    Most SS1000 analyzer systems are configured for use at extractive natural gas sampling stations. How the Analyzer Works The SS1000 analyzer employs tunable diode laser absorption spectroscopy (TDLAS) to detect the presence of trace substances in process gases.
  • Page 17 Introduction GAS OUT DETECTOR I(λ) LASER (λ) TRACE GAS ABSORPTION α(λ) GAS IN Figure 1–1 Schematic of a typical laser diode absorption spectrometer. Due to their inherent structure, the molecules in the sample gas each have characteristic natural frequencies (or resonances). When the output of the laser is tuned to one of those natural frequencies, the molecules with that particular resonance will absorb energy from the incident beam.

    Calibrating the Analyzer Calibrating the analyzer is typically not required under normal circumstances. SpectraSensors calibrates each analyzer to a National Institute of Standards and Technology (NIST) traceable standard before shipping the unit to the end user. Because SpectraSensors analyzers use a non-contact form of measurement, they are relatively insensitive to contamination, are quite rugged and virtually maintenance free ensuring years of reliable service.

    It is recommended the supply lines be Do not use plastic tubing of any kind for sample lines. Plastic tubing is permeable to moisture and other substances which can contaminate the sample stream. SpectraSensors recommends using 1/4" O.D x0.035" wall thickness, seamless stainless steel tubing.
  • Page 62: Contamination

    Secure tubing to appropriate structural supports as required. 8. Check all connections for gas leaks. SpectraSensors recommends using a liquid leak detector. Do not exceed 10 psig (0.7 barg) in sample cell. Damage to cell may result.
  • Page 63: Cleaning The Mirrors

    Secure tubing to appropriate structural supports as required. 8. Check all connections for gas leaks. SpectraSensors recommends using a liquid leak detector. Cleaning the Mirrors If contamination makes its way into the cell and accumulates on the internal optics, a Power Fail will result.
  • Page 64: To Clean The Mirrors

    9. Look inside the sample cell at the top mirror using a flashlight to ensure that there is no contamination on the top mirror. Due to its proximity to the optical head, SpectraSensors does not recommend cleaning the top mirror. If the top mirror is visibly contaminated, contact your factory service representative.

    Troubleshooting 14. With gentle, uniform pressure, wipe the mirror from one edge to the other with the cleaning cloth only once and only in one direction to remove the contamination. Discard the cloth. Never rub an optical surface, especially with dry tissues, as this can mar or scratch the coated surface.
