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. The aim of the invention is to examine spectrogams obtained by means of measurements for group-specific patterns, classify said spectrograms accordingly, and thereby determine the constituents. Said aim is achieved by a method according to the invention, characterized in that the sample is accommodated in a defined volume and separated chromatographically and spectrograms are created and are evaluated by means of evaluation software. The method is predominantly used to analyze volatile organic substances (VOCs) in respiratory air and other directly or indirectly obtained biological samples and to categorize said volatile organic substances in order to detect clusters and patterns that enable statements even without knowledge of the chemical structure of the individual substances. Fields of application are medical diagnostics, biotechnology, technology, analytical chemistry, but also health protection and medical precaution on the basis of emissions measurements and workplace measurements, which can be taken in a stationary manner and with respect to individual persons.
