Abstract
The present invention relates to a separating agent for solid-phase extraction which comprises core particles of a base material; a hydrophilic polymer layer formed on the surface of the particles; and a hydrophobic polymer layer formed on the surface of the hydrophilic polymer layer. The separating agent can be used in a cartridge or a column for solid-phase extraction and the latter can in turn be used in a variety of methods such as a method for concentrating a subject to be separated; a method for removing impurities; a method for solid-phase extraction of an environmental, medicinal and/or biological samples; and a method for pre-treating a protein component-containing sample.
