Process and device for detecting dust-associated substances

摘要

A process for detecting dust-associated substances wherein the dust to be analyzed is brought together with a solvent for eluting the substance to be detected from the dust. The particulate components are retained by means of a filter matrix while the solvent and the substances dissolved and/or suspended therein are transported through the filter matrix by capillary liquid transport. The solvent and the substances dissolved and/or suspended therein are transferred into a reaction matrix adjoining the filter matrix by capillary liquid transport. The substance to be detected is detected in the reaction matrix by means of a chemical and/or biochemical reaction or by the failure of a chemical and/or biochemical reaction to take place. A device for detecting dust-associated substances preferably contains, besides the filter matrix and the reaction matrix, a container for receiving the dust to be analyzed, wherein the container is in liquid connection with the filter matrix.
