Overview.

The pQA is a portable gas analyzer for analysis of dissolved gases in water, for use in the field at the riverbank, on boats and in mobile laboratories. The system is supplied in a Pelican case and can be powered by a 12 V supply for field use, battery and/or solar powered, or a 120 V supply for laboratory use.

The pQA is offered with interchangeable inlets with either a polydimethylsiloxane or a proprietary X44 membrane.

The X44 membrane provides higher sensitivity for rare earth gases and is used in groundwater studies. The polydimethylsiloxane membrane material provides high sensitivity for volatile organic compounds (VOCs) and is used in more general MIMS applications.
