Electron impact mass spectrometer

EISense

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

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