Protea - Model ProMass -Quadrupole Mass Spectrometer (QMS) Analyser System
Quadrupole Mass Spectrometer Analyser System for low volume, quick responding gas measuring with large dynamic range Protea’s ProMass analyser is a compact, robustly designed semi-portable Quadrupole Mass Spectrometer (QMS) instrument incorporating all the latest mass spectrometer and vacuum pumping technology. ProMass can be supplied in portable carry case or a 6U 19” rack module for on-line process measurements. QMS is a useful mechanism for gas analysis in ambient air or process applications, being able to detect and measure almost all gases with low detection limits and fast response.
A mass spectrometer measures the mass-to-charge ratio of the molecules in a sample by collecting and analysing the mass spectrum we can identity and quantify which molecules are present. The QMS within ProMass contains a mass filter that is made up of 4 parallel circular rods, hence the name quadrupole. With variable mass ranges of 0-100amu, 0-200amu or 0-300amu it is an instrument suitable for portable or fixed installations ideally suited to semiconductor production processes, ambient air measurements, leak testing and quality testing for the food industry.
