Abstract:
A process for detecting a substance associated with dust, the process comprising the steps:bringing together the dust to be analyzed with a solvent to elute the substance to be detected from the dust;using a filter matrix for retention of the particulate components;transporting the solvent and the substances dissolved and/or suspended therein through the filter matrix by capillary liquid transport;transferring the solvent and the substances dissolved and/or suspended therein into a reaction matrix adjoining the filter matrix by capillary liquid transport, said reaction matrix and said filter matrix having separate individual discrete areas which are not intermixed, said reaction matrix and said filter matrix adjoining each other in a fluid capillary connection;detecting the substance to be detected in the reaction matrix by means of a chemical and/or biochemical solid-phase reaction or by the failure of a chemical and/or biochemical reaction to take place.
