A bench-top membrane inlet mass spectrometer designed for analysis of gases, vapours and VOCs in liquids

Measures dissolved gases in liquids, sea water, estuary, soil core and headspace.

The Hiden HPR-40 DSA Membrane Inlet Mass Spectrometer (MIMS) is a compact bench-top gas analysis system for real-time quantitative analysis and monitoring of dissolved/evolved gases.

Overwiew

The system offers the facility for analysis to sub-ppb (parts per billion) levels and is suited to gas analysis applications where sample volume is small and for environmental applications where detection of a low concentration level is required. Both dissolved species probe inlets and circular membrane carrier inlets are available to address a broad range of applications. The inlet probe uses a special membrane that allows small levels of the dissolved species to pass through it and into the ion source of a high precision quadrupole mass spectrometer.

A manual isolation valve allows for control of the sampling and a solenoid safety valve provides protection for the mass spectrometer and vacuum system in case of membrane failure.
