A modular LabVIEW application frame for Knudsen Effusion Mass Spectrometry instrument control

Abstract

Knudsen Effusion Mass Spectrometry is an important research technique to determine the partial pressures of vapour species at equilibrium over different materials at a given temperature. The vapour pressure is one of the fundamental properties of a material and needed for any modelling involving temperatures where it is not negligible. Many research groups worldwide use Knudsen Effusion mass spectrometry techniques to determine vapour pressures of different materials. They usually develop their instrument and software themselves. The software, which is presented in the frame of this paper, targets to provide a modular LabVIEW software framework for the control and data acquisition of Knudsen Effusion Mass Spectrometry instruments that can easily accommodate any type of instrumentation.
