EISense
 Electron Impact - Mass Spectrometer

General

The EISense is a classic quadrupole mass spectrometer with electron impact ionisation (EI-MS). This analyzer is the entry level model into online multi component gas analysis from V&F.

The ionisation takes place at 70eV and the mass range is from 2 to 100 amu with a resolution of 1 amu.
