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.



▪ 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
▪ Dedicated software
▪ Built-in PID controller (optional)


The small size and relatively low weight allows easy transportation. The unit has its own pumping system, quadrupole mass spectrometer and inlet that allows for operation over a wide range of pressures with simultaneous mass analysis for 10 gases. As an option, the UMS can be equipped with PID and heating controllers for dedicated Thermal Desorption Spectrometry.
Full operation of the spectrometer is controlled by dedicated TDS software via Ethernet interface.
