Gas sampling system (GSS)

Reliable collection of air samples

The Gas Sampling System (GSS) is an active sampling system based on pumped sampling of air onto one or two adsorbent tubes, which are then analyzed by thermal desorption combined with GC/MS. The two flow channels may be used as independent, for Distributed Volume Pair samples or as identical channels for critical and unique samples.

Dual channel system – for improved safety

The GSS is equipped with mass flow controllers as well as mass flow sensors with Flow Tamer™ Technology. The GERSTEL GSS is compatible with all standard TD-tubes used for thermal desorption. All collection parameters are independently recorded on both channels and may be sent to an external data device. Sampling may be started using a pre-programmed time schedule or on-demand from the built-in touch screen.

GERSTEL GSS Features
