In a process that is used to detect substances that are associated with dust, the dust that is to be tested is brought together with a solvent in order to elute the substance that is to be detected from the dust. The specific constituents are contained by means of a filter matrix (2), whereas the solvent and the substances that are either dissolved and/or suspended therein are moved through the filter matrix (2) by capillary action. The solvent and the substances dissolved and/or suspended therein are transferred by capillary action into a reaction matrix that is adjacent to the filter matrix. The substance that is to be detected is indicated by means of a chemical and/or biochemical reaction or by the non-occurrence of a chemical and/or biochemical reaction. Apart from the filter matrix (2) and the reaction matrix (3), an apparatus to detect substances that are associated with dust has a container (1) that is used to accommodate the dust that is to be tested, the container (1) being connected to the filter matrix (2) in such that liquid can move between.
