Abstract: A device, process and system are provided for collecting and releasing a liquid sample, especially saliva. A defined saliva sample, i.e., a filtered, approximately homogeneously mixed saliva sample of a predetermined volume is made available in the simplest possible manner. A sampling tip (2) is provided made of a dimensionally stable and porous material, which is moved with its mouthpiece (4) in the mouth of a test subject for one to two minutes and takes up saliva based on the capillary action. A reagent liquid enters the pores of the sampling tip (2), mixes with the saliva there and is subsequently fed from a reagent depot by the action of pressure. The saliva and the reagent liquid are finally discharged as a droplet (40) in the filtered and mixed state, either into the cavity (10) of the sample collector or into a filter mixer.

Abstract: A device for collecting and releasing a sample liquid, especially saliva as well as a system and method are provided. The device and system obtains and provides a defined saliva sample, i.e., a filtered and homogeneously mixed saliva sample of a predetermined volume, in the simplest possible manner. The device has a sampling tip (2) made of an incompressible and porous material, which is moved with its mouthpiece (4) in the mouth of a test subject for 1 to 2 minutes and collects saliva based on the capillary action. A reagent depot containing reagent liquid is subsequently cut up by a puncturing cylinder (9) at the sample collector, and the reagent liquid then enters the cavity (10) of the sampling tip (2).

Abstract: A swab analyzer with advantageous handling and detection sensitivity for the immunochemical detection of substances. The analyzer has a housing, an eluent application zone (a swabbing pen 2) and a reaction zone (6). The housing (1) has a local elevation with a central opening, from which a sampling and eluent application zone, designed as a porous swabbing pen (2), projects. The local elevation is provided with an at least partially circular collection groove (3) for receiving excess eluent. A window (10) is present in the housing (1) at a spaced location from the local elevation for evaluating the reaction zone (6) placed under it. The sampling and eluent application zone as well as the reaction zone (6) with the signal zones (7) are in capillary fluid connection with one another.

Abstract: 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.
