摘要：
In a sampling head (1) of an analysis arrangement (31), provision is made that a sample stream delivered via a sampling line (2) and a dilution air stream delivered through a dilution air inlet (4) are mixed together in a dilution unit (3) in such a way that a volumetric quantity entrained in at least one receiving space moved along by a movable element (8) between the sampling stream and the dilution air stream are exchanged with each other, wherein the analysis arrangement (31) has a gas analyzer (35) for the analysis of the slightly diluted sample stream and a particle determination unit (32) for the analysis of the enriched dilution air stream.
