An Analytical Mass Spectrometer for the Gas Analysis

Abstract

The tentative construction of a mass spectrometer of π/2 (Hipple type) single magnetic focusing to be used for the gas analysis is described in this paper. The mass scanning circuit contains a new electronic device replacing the mechanically driven scanner which has ever been used. For the analytical works, due emphasis should be given to the maintenance of the overall stability of the instruments for a long period of time. However, some analytical results are reported prior to this routine analysis and also the effects of the electron emitter treatment for the stabilization of the sensitivity and the cracking patterns (mass spectra) are discussed.
