DEVICE AND METHOD FOR ANALYZING VOLATILE ORGANIC COMPOUNDS IN GASEOUS SAMPLES

摘要

The invention relates to a device and to a method for analyzing volatile organic compounds in gaseous samples, a sample being held in a defined volume and separated chromatographically. Spectrograms are created, preferably using DMS, evaluated by means of evaluation software, analyzed for group-specific patterns and classified accordingly. The method is predominantly used to analyze respiratory air and other directly or indirectly obtained biological samples and to categorize said samples in order to detect clusters and patterns that allow diagnoses, even without knowledge of the chemical structure of the individual substances.
