CONCENTRATION METHOD OF ION CHROMATOGRAPHY SAMPLE AND ION CHROMATOGRAPHY CONCENTRATION APPARATUS

Title:

CONCENTRATION METHOD OF ION CHROMATOGRAPHY SAMPLE AND ION CHROMATOGRAPHY CONCENTRATION APPARATUS

Document Type and Number:

Japanese Patent JP2005257459

Kind Code:

A

Abstract:

To provide a concentration method of an ion chromatography sample capable of passing an ion chromatography sample through a concentration column by sucking the ion chromatography sample using a suction device and pressurizing the same using an inert gas, and provide a ion chromatography concentration apparatus.

In the concentration method of the ion chromatography sample by sucking the ion chromatography sample using the suction device to pass the same through a concentration column, the filler of the concentration column is an organic porous ion exchanger with a mesophore radius of 0.1-100 μm and an ion exchange capacity of 1.0 μg equivalent/g.
