Environmental sampler for mass spectrometer

   
   

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.

Um sampler ambiental para um spectrometer maciço é divulgado que forneça para introdução controlada de quantidades pequenas de líquidos ou de gáses no sistema do vácuo do spectrometer maciço sob circunstâncias ambientais severas. As verificações exatas da calibração do sampler ambiental e do spectrometer maciço durante a operação autônoma remota são possíveis por meio de uma integral padrão interna do reservatório com o sampler ambiental.
