HPR 40 DSA, Membrane inlet mass spectrometer for dissolved species analysis

Made by a Hiden Analytical Ltd., UK, Website: http://www.hidenanalytical.com)
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.
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 insertion 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.
Applications:

+ Dissolved species analysis
+ Enviroment monitoring 
+ Fermentation
