ABSTRACT:
An apparatus (1) for processing or preparing liquid samples for a preferably quantitative chemical analysis, especially for flow-injection analysis, is, for the purpose of miniaturisation and reducing the necessary sample volume while at the same time reducing the analysis time, assembled from a set of plate-like components (8). Each of the components (8) includes channels to form pipe pieces (9) and/or branches (13) with orifices and/or values, for example non-return valves, and/or pumps (6,7) in order to be able to feed the carrier liquid and sample to a detector (3) in the desired manner. Depending on the purpose of the analysis, the components (8) with the pipes and functional parts contained in them may be stacked in varying number and/or sequence and/or angular orientation relative to one another and can be connected in a sealing manner in the operative position.
