Unisearch Associates Inc.

Unisearch Associates was founded in 1980, and has since become a world leader in the development of gas measurement technology based on Tunable Diode Laser Absorption Spectroscopy (TDLAS). We manufactured and patented our first instrument, the high-sensitivity (sub-ppbv) LUMINOx NO2 monitor, for commercial use four years after our establishment. Several hundred units were sold prior to our divestiture of the technology in 2005, following a change in the company’s focus to optical products and their applications. We are now dedicated to innovating Tunable Diode Laser (TDL) and Differential Optical Absorption Spectroscopy (DOAS) technologies for gas emissions monitoring across a wide range of industries. Applications of these technologies include process control and regulatory measurement.
