ABSTRACT:
An environmental sampler for a mass spectrometer is disclosed that provides for controlled introduction of small amounts of fluids or gases into the vacuum system of the mass spectrometer under severe environmental conditions. Accurate calibration checks of the environmental sampler and mass spectrometer during remote autonomous operation is possible by means of an internal standard reservoir integral with the environmental sampler.
