Concentrate sample raw material mixtures, useful for the preparation of samples for the analysis of pesticides, comprises a chromatographic cleaning stage, separation into flow paths and analysis

摘要

Concentration of sample raw material mixtures (2) into small volumes, comprises: (1) physical/chemical processing in a chromatographic cleaning stage (3); (2) separation (5) into flow paths (5a,5b...5n) to individual concentration stages (6a,6b...6n), to be processed into given concentrations; and (3) passing on (7a,7b...7n) for further processing and analysis (8). Concentration of sample raw material mixtures (2) into small volumes, comprises: (1) physical/chemical processing in a chromatographic cleaning stage (3); (2) separation (5) into flow paths (5a,5b...5n) to individual concentration stages (6a,6b...6n), to be processed into given concentrations; and (3) passing on (7a,7b...7n) for further processing and analysis (8). The mixtures are fed directly during their formation in the concentration processes. The sample material is fed through automatically to give a continuous flow process. The concentration stages are controlled separately, in relation to the sample materials.
