Although Western Research is best known as the world leader in providing analyzers for the sulfur recovery industry, our 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. We 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.

We have pioneered a number of applications that are key to the efficient and clean operation of many processes such as:

• tail gas analysis for sulfur recovery (also feed gas, pit gas, TGTU control, and thermal oxidizer emissions)
• stack gas emissions monitoring for sulfur dioxide (SO₂)
• multi-point analysis of sulfuric acid production processes
• hydrogen sulfide analysis of pipeline quality natural gas using frontal elution chromatography with UV photometry
• automated chilled mirror for on-line hydrocarbon dew point monitoring of natural gas for pipeline networks
• vanadium in TiCl4 for titanium and titanium dioxide production
• color of liquid hydrocarbons for refining process control
• detection of antibiotics and active ingredients in pharmaceutical processes
• water in acetic acid for acetic acid manufacture
• ammonia and ammonium nitrate for fertilizer production
• phenol in wastewater for metal production and environmental monitoring
• chlorine purity and residual chlorine analysis
• chlorine dioxide for pulp and paper bleaching
• TNT in wastewater for environmental protection
• and many other applications too numerous to list here

The Western Research photometric products are manufactured in our Calgary, Alberta, Canada and our Newark, Delaware, USA facilities.
