Some Aspects of Quantitative Gas Analysis by Quadrupole Mass Spectrometer

摘要

In spite of keeping conditions constant during various measurements, interpretations of gas analytic mass spectra were often found to be difficult as, apparently, cracking patterns are not constant. This happens e.g. in case of variations of pressure during the measurement. Some possible effects (charge transfer processes in the high-pressure range, contributions from surface ions in the low-pressure range) have been studied and are discussed in the presentation.
