METHOD AND DEVICE FOR DETERMINING A FOREIGN SUBSTANCE CONTENT IN A MATRIX

摘要

The invention relates to a method and to a device (100) for determining a content of at least one foreign substance (89) in a matrix (88) of a solid or liquid food, characterized by at least one reagent area (40) for providing at least one reagent (58) having a receptacle (41) for a replaceable reagent container (62) for replaceably connecting a sample container (80) comprising at least the matrix (88); a transfer line (13) between the reagent area (40) and the reaction area (60), by means of which the at least one reagent (58) can be fed to the reaction area (60); a sensor area (90) for demonstrating the foreign substance (89) released from the matrix (88); a carrier gas line (15) between the reaction area (60) and the sensor area (90), by means of which the released foreign substance (89) can be fed to the sensor area (90); and an output line (17) through which the dissolved foreign substance (89) can be fed outward from the sensor area (90).
