Although Western Research is best known as the world leader in providing analyzers for the sulfur recovery industry, their photometric and spectrophotometric process analyzers are used in wide variety of industries worldwide for reaction monitoring and control, emissions monitoring, feedstock monitoring, and product quality assurance. They produce a carefully engineered selection of single wavelength, multi-wavelength, and broad spectral
analysis instruments for rack mount and industrial field installation. These instruments can be adapted to a tremendous variety of applications and end uses.
Western Research
A wide range of standard and custom-built industrial UV-Vis photometric analyzers for various chemical composition analyses of inert, reactive, and toxic gases or liquids. Used to monitor or control: feedstock quality, reaction rates, quality control/assurance, blending analysis, pollutants, etc.

Model 9000RM Gas Analyzer Download printable brochure.
NEW GENERATION! REPLACES MODELS 921 AND 922.
The AMETEK Model 9000RM is a rugged single or multi-component gas analyzer housed in a single 19-inch, rack-mountable unit that can be integrated into Continuous Emission Monitor Systems (CEM) or used alone for a variety of gas monitoring applications.
The Model 9000RM can be configured to measure most gas species that absorb in the UV (examples NOx, H2S and SO2). The optional low range white cell provides longer path length for measuring lower concentrations. For example, the minimum full scale for SO2 is 25 ppm, with an accuracy of 1% of full scale.
Resolution better than 0.02 nm is provided by high intensity, line source lamps. These sources emit at a fixed wavelength, providing great measurement stability, and emit low total power, removing the potential for sample photolysis. The high resolution enables unparalleled linearity over a wide dynamic range (less than 1% deviation over 4 to 5 orders of magnitude) which, in turn, leads to simple, robust data analysis.
