AMETEK , PROCESS INSTRUMENTS A PRODUCT DATA SHEET MEASURES: H2S (H2) 931 Single-Gas Analyzer Sophisticated UV-VIS photometer measures any single UV-absorbing gas species for process monitoring and control This rugged, single-ultraviolet (UV) component photometric gas analyzer is housed in an explosion-proof package. Typically measuring hydrogen sulfide (H2S), the 931 is designed for a variety of gas monitoring and process control applications and is a "hot-wet" analyzer with a heated cell oven to avoid hydrocarbon or water condensation. A fully integrated sample system ensures reliable dew point control without running the risk of plugging, contaminating, or flooding the analyzer. Many process applications require the detection of species which do not absorb in the ultraviolet spectrum. The 931 may optionally be provided with a thermal conductivity detector (TCD) for the measurement of hydrogen (H2). The unit can also be configured for sulfur dioxide (SO2) , carbonyl sulfide (COS), carbon disulfide (CS2) or ammonia (NH3) as the primary measurement. No matter what the need is, this flexible, low-maintenance analyzer design is the answer to many of today's complex process control requirements. Fixed optical configuration Instead of using a filter/chopper wheel to alternate between measure and reference wavelengths, the 931 uses a fixed optical configuration and pulsed UV lamps. This design leads to increased light throughput, reduced noise levels, and reduced maintenance. Unparalleled linearity Resolution of better than 0.02 nm is achieved with high-intensity, low-energy hollow cathode UV source lamps. These lamps emit UV radiation at precise wavelengths. The construction of the UV lamp determines the wavelength of interest, making it possible to configure this analyzer to measure many components that absorb UV/VIS energy. This high-resolution design enables unparalleled linearity over a wide dynamic range (less than 1% deviation over three to four orders of magnitude), which leads to simple, robust data analysis. • No moving-parts design • Measurement of additional species optionally available (thermal conductivity detector) • Sample can be returned to process (with HAG probe option) • Low-maintenance design • Minimal span drift • Stream-switching capability B9 APPLICATIONS • Amine-based tail gas treating (optional H2) • SRU feed gas analysis • Well head gas • Sour gas pipelines FI KEY MARKETS • Sulfur recovery • Tail gas treating • Sour gas pipeline Application flexibility Whether it's reliable high concentration H2S, monitoring of sour gas pipelines, or process control of SRU tail gas treating units, this single-gas analyzer is the best choice for reliable, field proven, and rugged single-species measurement applications.
