• Multifunctional Wide Range Pressure Mass Analysis
  • System for Thermal Desorption Spectroscopy (TDS)Prevac UMS


The device is equally suited for use in scientific and industrial fields. It can be used for gas analysis and thermal dysorption experiments.

The device operation is controlled by a microprocessor control unit equipped with large LCD graphic display. Such a combination of easy and user-friendly interface allows for full automatic pumping and venting process and the same protection of all built-in components.

Small size and relatively low weight allow easy transportation. The unit has its own pumping system, quadrupole mass spectrometer and vacuum equipment which allow for operation in wide range of pressures with simultaneous mass analysis for
10 gases. As an option, the device can be equipped with PID and heating controllers for precise temperature changing and stabilizing, which is required in Thermal Desorption Spectroscopy.

Full operation of the spectrometer is controled by dedicated software installed on any PC computer compatible with USB interface.


  • Precise mass analysis of gas composition in range to 100, 200 or 300 AMU of the gases from experimental chambers, owens, or reactors.
