pQA – Portable Quadrupole Analyser A compact transportable case mounted gas analyser configured for environmental field studies.

Detailed product information / introduction Water analysis Environmental monitoring Swimming pool analysis pQA a compact transportable ruggedized case mounted gas analyser configured for environmental field studies. MIMS – membrane inlet mass spectrometry provides a sample interface for liquids and gases/ vapours to the mass spectrometer analyser. The choice of membrane and inlet employed provides application specific enhancements. The pQA is offered with interchangeable inlets with either Polydimethylsiloxane or a proprietary X44 membrane. Applications: XXGround water studies XXVolatile...
