Purge & Trap

Chromatotec (France) have developed an analyser for the identification and measurement of volatile organic compounds in air and water. The Purge & trap apparatus extracts VOC compounds from water in compliance with 502.2 method (US EPA: 60 compounds).

This solution is convenient for a wide range of applications such as: raw source water, river water, seawater, rain water, finished drinking water, bottled water analysis and surface water. More specifically, the detection range varies from 0.5 to 20µg/L for surface water and for finished drinking water.

In order to be analysed, 5mL of water sample are inserted inside a sparger. Then, an inert gas is needed to purge the sample and to send the gaseous compounds to the detector. Finally, the detector identifies and quantifies the compounds. The sampling time occurs over 11 minutes and an automatic rinse is done after the measurement.

This cabinet is the perfect solution for all kinds of water analysis or surveillance.
