AMETEK A PROCESS INSTRUMENTS ^ PRODUCT DATA SHEET 932 Multi-Gas Analyzer Sophisticated ultraviolet (UV) photometer measures up to five UV-absorbing gas species for process monitoring and control The 932 is a rugged, multi-component UV photometric gas analyzer housed in an explosion-proof package designed for a variety of gas monitoring and process control applications. Hydrogen sulfide (H2S) is frequently the primary measured component, along with sulfur dioxide (SO2). The 932 can also be configured to measure carbonyl sulfide (COS) and/or carbon disulfide (CS2), when end users are required to measure these sulfur species for regulatory or process efficiency reasons. COS and CS2 can poison some catalysts used in sulfur recovery units, driving up operating expenses at the plant. The 932 uses a dual beam design, with one detector used as a reference to reduce drift. Span drift is further minimized through the use of a hollow cathode lamp that is extremely stable over temperature changes and/or time. The hallow cathode lamps also have very narrow emission lines, improving linearity when compared to dispersive or non-dispersive broadband light sources. The optical assembly in the 932 supports the simultaneous generation and detection of multiple wavelengths, enabling users to measure multiple analytes of interest, or even different ranges of a singe analyte, with one analyzer. Many process applications require the detection of species which do not absorb in the UV spectrum. The 932 may optionally be incorporated with a thermal conductivity detector (TCD) for the measurement of hydrogen (H2), or infrared sensors for the measurement of hydrocarbons or carbon dioxide (CO2). Condensation solution For those applications where sample condensation may occur, the 932 analyzer system is available with a heated cell option. The fully integrated heated cell ensures reliable dew point temperature control without running the risk of plugging, contaminating, or flooding the analyzer.
