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

Handheld sampling-removal head, analysis arrangement and method for characterizing an aerosol

A method for determining an NOconcentration in a measurement gas is provided, where a measurement value for the NOconcentration is determined from the sensor signal of a gas sensor and a measurement value for the concentration of a second component in the measurement gas is determined. A corrected value for the NOin the measurement gas is determined from the measurement values, and the measurement value and the corrected measurement value for the NOconcentration are displayed and/or output.
