Abstract
A new approach to the GC/MS identification of organic components of the atmosphere is proposed. It is characterized by the use of averaged values of retention indices of different types at different temperatures in combination with several main peaks of mass spectra and allows considerable standard deviations of indices and peak intensities. Hence, it is possible to achieve good interlaboratory reproducibility of results working with simplest computers having a small operative memory. The data base contains averaged eight-peak mass spectra and retention indices on polymethylsiloxane stationary phases for about 600 volatile organic compounds constantly present in atmospheric air or those that should be checked in populated areas.
