摘要

研制了一种测量环境空气中BTEX化合物的UV-IBBCEAS光谱仪，并对其进行了表征。该仪器在60秒的测量时间内达到了<5 ppb的检测限。该光谱仪用于研究来自城市环境的排放，其中在加油站附近观察到BTEX水平升高。

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

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.
