ACTI-VOC™ is a robust low-flow pump for sampling vapour-phase organic compounds (VOCs) onto sorbent tubes for subsequent analysis by thermal desorption (TD).

Being lightweight, easy-to-use and intrinsically safe, ACTI-VOC is ideal for personal monitoring and a wide range of other air and gas sampling applications.

Optimised for thermal desorption tubes

Unlike other personal monitoring pumps on the market, ACTI-VOC is optimised for sampling onto thermal desorption tubes, and automatically compensates for different impedances, ensuring constant flow rates whatever the sorbent packing.
