Title:
【発明の名称】有機被検体の痕跡量の改良された固相ミクロ抽出
Document Type and Number:
Japanese Patent JP2867237
Kind Code:
B2
Abstract:
A method for enhancing detection sensitivity of suspected trace amounts of organic analytes and particularly semivolatile organic analytes extractable from a sample by an organic solvent carrier matrix and subsequent extraction and analysis of said trace organic analytes by SPME wherein the improvement comprises exchanging the organic solvent carrier matrix containing the trace organic analytes for an aqueous carrier matrix before performing SPME fiber extraction and detection of the trace organic analytes. The diagram, a chromatogram obtained with an ECD detector, illustrates the determination of chlorinated pesticides at the sub-parts per trillion level.
