Verfahren und Anordnung zum Erkennen komplexer Gas-, Geruchs-, Aromamuster einer jeweiligen Substanz auf der Basis der Massenspektroskopie

摘要

The invention relates to a method and device enabling time-saving, comparative mass spectrographic analysis of serial samples corresponding to a reference, for example serial samples of a product, by conditioning by means of a reference sample and forming a pattern of a reduced number of fragment ions, said fragment ions having been selected from individual mass spectrums of the same separated by gas chromatography, and forming a pattern of a reference random sample from overall mass peak spectrograms of several reference samples reduced accordingly.
