Abstract
A technique for automatically analyzing mass spectrographic data from mixtures of chemical compounds has a series of screens designed to eliminate or reduce incorrect peak identifications due to background noise, system resolution, system contamination, multiply charged ions and isotope substitutions. With such a technique, mass spectrograph data analysis may be greatly simplified by the identification of probable spurious signals, and analysis will become simpler and more accurate.
