Title:
試料を調製し、農薬を分析するための、ＨＩＬＩＣクロマトグラフィカラムの装置およびＳＰＥ濃縮装置
Document Type and Number:
Japanese Patent JP5855100
Kind Code:
B2
Abstract:
An arrangement for preparing samples and analyzing pesticides in samples contains an HILIC chromatography column with a first pump for a predominately low-water and/or non-polar solvent; and SPE enrichment arrangement; a second chromatography column with a second pump for a predominantly water-rich and/or polar solvent; a detector; and a valve arrangement for controlling the stream of sample and matrix, which valve arrangement is designed in such a way that the sample stream, in a first switching state of the valve arrangement, can be conducted from the HILIC chromatography column to the SPE enrichment arrangement and, in a second switching state, the sample enriched in the SPE enrichment arrangement can be conducted in the opposite direction from the SPE enrichment arrangement through the second chromatography column to the detector.
