A UV-Broadband Cavity-Enhanced spectrometer for the sensitive monitoring of BTEX in ambient air

Abstract

A UV-IBBCEAS spectrometer to measure the BTEX compounds in the ambient air was developed and characterized. The instrument achieved a detection limit of <5 ppb for a measurement time of 60s. This spectrometer was used to study the emissions from an urban environment, where an elevated level of BTEX was observed near to a gas station.
