The 9933 builds upon the proven success and performance of the 933 gas analyzer, to accurately measure and report hydrogen sulfide (H2S), carbonyl sulfide (COS), methyl mercaptan (CH3SH) and other components of interest, in fully redesigned configuration. The 9933 is capable of field mounting, with an integrated heater and sample conditioning system, designed to operate within a wide ambient temperature range: -20°C – 50°C is standard, with a -20°C – 60°C configuration optionally available. The analyzer is IP66 rated, fully protected against wind, rain, and dust.
The analyzer also includes a large touch screen user interface, that provides detailed analyzer information without requiring a laptop.
The 9933 can be configured to measure additional components that may be present in traditional natural gas streams, including hydrogen and carbon dioxide.
Interference free measurements
The 9933 utilizes unique and proprietary frontal elution chromatography to separate H2S, COS, and CH3SH from interfering components in natural gas. Two long-life columns are employed in the 9933. While the first column is conditioning the gas sample, the standby column is automatically regenerated.
Accurate performance
Non-dispersive, dual-beam hollow cathode ultraviolet (UV) photometric detection of H2S, COS and CH3SH provides accuracy better than ±0.25 ppm. Infrared and TCD technology are used to provide optional CO2 and H2 measurements.
The 9933 uses no consumables or reagents and is designed for outdoor installation – Find out more.
