Sigma borosilicate type Volatile Organic Chemical sampling vial

Passive air sampling for semi-volatile organic chemicals

A distinct set of PASs has been developed for semi-volatile organic chemicals (SVOCs). The term SVOCs comprises organic molecules that can occur to a significant extent in both the gas-phase and condensed phases, which corresponds to the vapour pressure range of approx. 10 −1 to 10 −6 Pa. The group of SVOCs comprises a large number of
