AMETEK PI - Model 932 -Multi Gas H2S Analyzer

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 single analyte, with one analyzer.

Fully parts-compatible with the 9xx suite of sulfur recovery analyzers, the 932 provides a multi-gas monitoring and control solution for applications in the hydrocarbon processing industry.

DUAL BEAM DESIGN
The 932 uses a dual beam configuration, 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.

OPTIONAL TCD/INFRARED SENSORS
For the detection of species which do not absorb in the UV spectrum, the 932 may optionally use 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
The 932 is available with a heated cell option for applications where sample condensation may occur. The fully integrated heated cell ensures reliable dew point temperature control without running the risk of plugging, contaminating, or flooding the analyzer.

The 932 is a UV multi-gas photometric analyzer for process monitoring and control – Find out more.
