Membrane Inlet Gas Analyser
The MAX300-LG Membrane Inlet Mass Spectrometer Gas Analyser (MIMS) is a fully automated Quantitative Gas Analysis system with a temperature controlled Membrane Introduction Inlet for fast and repeatable analysis of gases and dissolved gases in liquids at the parts-per-trillion level.
Quantitative Gas Analysis, performed with precision, accuracy and repeatability, demands an analyser with exceptional stability & repeatability characteristics coupled with an inlet system and analysis methods that can handle routine calibrations and background gas subtractions.
The MAX300-LG Membrane Inlet Mass Spectrometer delivers all this, plus the ability to significantly extend the detection range for many compounds down to the ppt level via enrichment through the semi-permeable membrane. Both gases and dissolved gases in liquids may be analysed.
As standard it is configured with our highest specification 19mm quadrupole rod set, dual Faraday cup/Electron Multiplier detectors, temperature stabilised ion source, and 4 channel chemically inert auto-controlled inlet valve (expandable to 16 streams). Not only does this combination offer best in class stability and repeatability characteristics, it is backed by our industry leading Questor5 quantitative analysis control platform which features fully automated analysis routines that measure and deconvolute background gas interferences and overlapping fragment peaks. This is combined with automatic calibration stream analysis and a 180 component internal fragment pattern library to deliver single click quantitative analysis of unlimited components with a cycle time of 300msec per component.
All this is backed by our no-nonsense application review service which provides you with a written statement of expected precision and repeatability of analysis for each component in your gas mixture - taking the guesswork out of quantitative gas analysis.

Mass Spectrometer Membrane Inlet for PPT Gas Analysis:
The membrane inlet cell delivers sample gas or liquid through a heated path and across the membrane which transmits the sample into the low pressure ion source region of the mass spectrometer. Sample and membrane are at the same constant temperature which gives repeatable and stable measurements throughout.
