摘要： The invention relates to a method and device enabling time-saving, comparative mass spectrometric 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 selected from individual mass spectrums of the same separated by gas chromatography, and forming a pattern of a reference random sample from overall mass spectrograms of several reference samples reduced accordingly.
