METHOD OF ANALYZING MINUTE QUANTITY OF CONTENT

WIPO Patent Application WO/2005/052552

A1

A method in which sample preparation for analyzing minute quantities of contents of a material can be carried out by one-time brief extraction treatment without need to conduct prolonged extraction treatment to thereby attain rapid analysis of minute quantities of contents of a material. This method of analyzing minute quantities of contents comprises the steps of disposing a sample piece of analyte material on a sample stage; dropping on the sample stage a solvent for extracting contents from the sample piece so that the solvent penetrates into the interstice between the sample stage and the sample piece disposed on the sample stage; holding at room temperature the solvent having penetrated into the interstice between the sample stage and the sample piece so that contents are extracted from the sample piece by the solvent held in the interstice between the sample stage and the sample piece; and analyzing the contents having been extracted from the sample piece.
