Membrane Inlet Mass Spectrometer Explained

The Hiden Analytical HPR-40 Membrane Inlet Mass Spectrometer (MIMS) system uses a semi-permeable membrane to isolate the mass spectrometer from the aqueous media and preferentially transmit the dissolved gases and organic vapours for analysis, simultaneously and continuously measuring multiple species in realtime.Sampling options comprise a range of circular carrier interfaces for flow-through operation and of capillary-style probes for direct insertion into the media. The Hiden HPR-40 addresses a broad range of applications including soil core analysis, water analysis, groundwater contamination studies and environmental monitoring. Hiden Analytical have published their latest brochure which describes the HPR-40 MIMS for measurement of dissolved gaseous species in aqueous solution. The brochure outlines features and specifications of the instrument together with an overview of the HPR-40 methodology and application areas.
