Complete Solution for Tracking VOCs in Water and Air

Chromatotec (France) has developed a unique analyser for identification and measurement of volatile organic compounds both in air and water.

The airmoPurge extract VOCs from water in compliance with 502.2 method (US EPA: 60 compounds).

Associated with VOCs analysers, this complete solution offer capabilities to track VOCs in industrial or dirty water. It is convenient for a wide range of applications such as: dirty water, river water, rain water, finished drinking water, bottled water analysis and surface water in addition to ambient air.

No need to go and change the configuration, the system is able to change from liquid to gas without human intervention.

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 (e.g. nitrogen is used 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 during 11min and an automatic rinse is done after the measurement.

With airmoPurge analyser, it is now possible to detect contamination of river in case of industrials spills due to the rainwater falling; this may occur contamination due to hydrocarbons or VOCs presence.

Same solution can be designed with Sulphur analyser for individual sulphur quantification in water.
