摘要： A method for extracting a component in a sample in solid phase in order to provide means effective for pretreating a sample being introduced to a chromatograph. The method comprises a step for providing a needle at the forward end of a syringe having a tube and a plunger slidable in the tube, forming a porous body of so-called monolithic structure in the needle at least over a proper length and the entire diameter and then inserting the needle into a sample, a step for passing the sample through the needle and holding a target component in the porous body, and a step for separating the target component from the interior of the porous body.

摘要： An object of the present invention is to provide effective means for pre-treatment of a sample to be introduced in a chromatograph, and the present invention is a method for performing solid-phase extraction of a component present in a sample, which uses a syringe having a cylinder and a plunger slidable within the cylinder, a tip of the syringe being provided with a needle and the needle being provided with a porous body having an so-called monolithic structure along at least an appropriate length of the needle and across an overall diameter of the needle, including the steps of inserting the needle into the sample, passing the sample through the needle to retain an analyte within the porous body, and desorbing the retained analyte from the porous body.
