Cerex offers both UV-DOAS and FTIR technology based analyzers so you can target your gases of interest at the lowest detection limits possible. Depending on your application, there will be pros and cons to each option.

Generally, UV-DOAS based analyzers are the most cost-effective choice for focusing on a few different gases with extreme sensitivity. In contrast, FTIR based analyzers come at a higher price tag but are highly adept at monitoring dozens of gases simultaneously – with laboratory sensitive quality.
