Abstract
Mass and ion abundance calibration of gas chromatograph/mass spectrometer responses is essential for the production of good data. In 1975, ion abundance criteria based on the mass spectrum of decafluorotriphenylphosphine (DFTPP) were proposed to standardize quadrupole mass spectra against magnetic sector spectra. This paper reports an investigation of DFTPP ion chemistry with the determination of the effects of some gas chromatograph/mass spectrometer operating parameters on the mass spectrum of DFTPP. New ion abundance criteria are proposed and discussed in relation to the findings of this investigation.
