Universal Mass Spectrometer UMS

Universal Mass Spectrometer UMS

The UMS is equally suited for use in scientific and industrial fields. It can be used for a variety of gas analysis and thermal desorption experiments. Operation is fully controlled by a microprocessor control unit equipped with a large 7” TFT LCD touchscreen. Such a combination of easy and user-friendly interface allows for full automatic pumping and venting together with complete protection of all built-in components.



Prevac are a world leader in the design and production of analytical and deposit scientific and research equipment. Their systems operate in a high and ultra high vacuum environment. They design and construct UHV and HV systems fully adapted to the individual requirements of research projects and industrial applications.

Key Features

  • Fast measurements
  • New highly flexible capillary
  • Easy capillary unblock feature
  • Small size and light weight
  • New, more effective turbo pump
  • Intuitive and user friendly interface with large 7” LCD touchscreen
  • Easy to use
  • Silent working
  • Data storage and analysing
