Abstract
Over 1400 electron ionization mass spectra of selected organic compounds have been measured under carefully defined conditions. In this paper, the variables such as sample purity and spectrometer calibration that are controlled are described. The quality of the resulting spectra as well as the cost of the measurements is reported.

A numerical rating for evaluating the qnality of reference maw spectra used for retrieval and interpretive applications is proposed. The overall quality index is the product of seven quality factors: (1) 8oorce of the spectrum; (2) ionization conditions; (3) higher m o l e d u weight impurities; (4)
The thermal degradation of a standard (sample 1) and five resin-modified paints has been investigated by pyrolysis-field ionization mass spectrometry (Py-FIMS). The modifications simulate possible industrial disturbances: cross-linker modification (omission of methyl melamine: sample 2, replacement
