Abstract

An exhaust-gas sampling system includes a main conveying line, a main throughput pump which conveys a sample gas in the main conveying line, a sample gas bag, a sample gas withdrawal line which fluidically connects the main conveying line to the sample gas bag, a throughflow control element arranged in the sample gas withdrawal line, an analyzer, a sample gas analysis line which connects the analyzer to the sample gas bag, an evacuation line which establishes a fluidic connection between the main throughput pump and the sample gas bag, and a first valve arranged in the evacuation line. The first valve opens and closes the evacuation line.
