摘要

A sample from individual items may after extraction be analyzed for the contents of one or more fat-soluble compound(s) by HPLC chromatography, the separation column during injection of the analysis sample being protected by means of a precolumn which during the further course of analysis is switched out of serial connection with the separation column so that it may be purified by flushing with appropriate fat-soluble agents. The apparatus for carrying out the method is composed of standard HPLC components. The method may be used for detecting or sorting-out such individual items for which the analysis results show excess of a predetermined threshold value of the fat-soluble compound(s) searched for.
