摘要:
The present invention relates to a method for repetitive chemical analysis of a gas flow, wherein said gas flow consists of a carrier gas and gaseous chemical compounds, comprising the following method steps: feeding said gas flow to a gas chromatographic separation column (42) by means of a feeding device (3); collecting at least a part of said gaseous chemical compounds for a defined time period by means of a thermally based collecting device (41) which is coupled to said gas chromatographic separation column (42) and/or said feeding device (3); releasing said collected gaseous chemical compounds in a temporally focused manner by means of said thermally based collecting device (41); separating said released gaseous chemical compounds by means of said gas chromatographic separation column (42); and analyzing said separated gaseous chemical compounds by means of an analyzer (5). The present invention further relates to a device (1) for performing such a method.
