CombiSense
 Ion-Molecule Reaction & Electron Impact - Mass Spectrometer

General

The CombiSense is a combination of an Electron Impact (EI-MS) and an Ion-Molecule Reaction (IMR-MS) mass spectrometer in one analyzer unit for a broad range of applications.

This enables you to measure the main components in the volume percent range simultaneously with trace gases in the ppm and ppb level.
