We are dedicated to the development of new analytical instruments for atmospheric and environmental measurements. While our specialization has always been in miniaturized instruments for measurements of ozone (O3), nitric oxide (NO), nitrogen dioxide (NO2), and mercury (Hg), we have long since grown to include numerous other chemical species in air. Our goal has always been to use sound science and innovative technology to provide our customers with cutting-edge instrumentation. A commitment to quality infuses everything we do toward that goal, and is how we maintain certification under the ISO 9001:2015 international quality standard.
