Stauffer, J. INTERPRETATION OF LOW RESOLUTION MASS SPECTRA FOR LEVEL 1 ANALYSIS OF ENVIRONMENTAL MIXTURES. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/7-82/033 (NTIS PB82232455), 1981.
Description:
The report gives guidelines for interpreting the low resolution mass spectra (LRMS) of complex chemical mixtures, within the context of the EPA Level 1 Environmental Assessment Program. It discusses the principles underlying direct mass spectrometric analysis of complex mixtures, the techniques for optimizing the analysis run, and the interpretation and evaluation of the results. A chapter gives some interpretive aids for LRMS analysis of environmental mixtures. The guidelines are illustrated by a step-by-step detailed analysis of the mass spectra of four representative examples. The final chapter gives direction for reporting the results in the EPA Level 1 LRMS format. These guidelines supplement the overall description of Level 1 analysis methods given in the IERL-RTP Procedures Manual: Level 1 Environmental Assessment (second edition), EPA-600/7-78-201 (NTIS PB 293795).
