Chemical analysis apparatus and method

摘要

A method and apparatus for the determination of an analyte in a liquid sample, the method and apparatus employing a liquid-permeable solid medium defining a liquid flow path. The medium includes one or more reactant-containing reaction zones spaced apart along the flow path and in which reaction occurs with the analyte or an analyte-derivative (e.g. a labelled analyte) to result in the formation of a predetermined product. Detector means are employed to detect analyte, analyte derivative, reactant or predetermined product in one or more reaction zones, the number of such zones in which such detection occurs reflecting the presence of analyte in the liquid.
