Overview.

The inlet probe uses a permeable membrane that allows small levels of the dissolved species to pass through it and onto the ion source of a precision quadrupole mass spectrometer. A manual isolation valve allows control of the sampling and a solenoid safety valve provides protection for the mass spectrometer and vacuum system in case of membrane failure.

The system offers analysis to sub-ppm levels and is suited to gas analysis applications where sample volume is small, and to 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.

Typical applications

Soil core analysisWater analysis in estuary, river or reservoirGroundwater contamination studiesMethane production controlMicrobiological and enzyme activity studies

Key Features.

  • Manual isolation valve and solenoid safety valve protecting the mass spectrometer and vacuum system in case of membrane failure
  • Optional 4 or 8 way multistream selector for multiplexed simultaneous sampling from up to four or eight reactors
  • Circular membrane carrier inlet for the analysis of flowing samples, with sample flow across the membrane
