Passive sampling

Quantitative passive (diffusive) sampling of trace VOCs in air

Passive (diffusive) sampling is an easy‑to‑use, low‑cost option for reliable time‑weighted-average (TWA) monitoring of a wide range of target organic volatiles in air. With a choice of three formats, Markes’ passive samplers are ideal for routine work, for large-scale studies, and for monitoring human exposure. Markes’ new extended range of passive samplers combine with analysis by thermal desorption (TD) and GC(–MS), to offer quantitative, high‑sensitivity monitoring of organic vapours in air at sub-ppb to high ppm levels, in full compliance with international standard methods.
