Data Processing System for the Measurement of Thermal Desorption Spectrum using a Personal Computer

Abstract

A data processing system for the thermal desorption specturm has been described. This system is constructed of a personal computer with an interface of intelligent type combining with a conventional quadrapole mass analyzer. One spectrum of mass number ranging from 1 to 50 can be obtained in a second with a rapid scanning technique. Besides, measurements of 120 times can be repeated at every other second in a single run. Thermal desorption spectra were demonstrated for two kinds of stainless steel sheets. Hardware and software of the system are also described.
