Vacuum Solutions for Your Mass Spectrometry Application | Pfeiffer

Low pressure conditions which minimize collisions between ions and residual gas molecules. This allows ions to travel efficiently from the ion source to the detector without scattering or neutralization.

High-Vacuum Pumps in Mass Spectrometers

High-Vacuum Pumps in Mass Spectrometers last regular installment of this col-umn covered basic vacuum concepts relevant to mass spectrometry. We reviewed basic gas parameters, such as

5 Mass Spectrometer Components – Mass Spec Academy

So, when working correctly, a mass spectrometer needs a low pressure and (thus) a long mean free path. However, analyzing a sample, by definition, adds stuff to the instrument and makes the vacuum

Spectrometer

Besides the two main characteristics of a spectrometer —namely, collecting power and resolution—there are a number of other features that determine the potentialities of a particular
