ABSTRACT:
Described is a copolymer of methacrylic acid and ethylene glycol dimethacrylate which does not have any specificity to general organic solvents, can thus adsorb wide variety of the organic solvents, shows almost no desorption-adsorption hysteresis and therefore, is excellent in desorption characteristics. Also described is a method for the preparation of the copolymer; an adsorbent or a concentrating medium comprising the copolymer; a loop used in an injector for chromatography which is packed with the adsorbent or concentrating medium; a needle for solid-phase microextraction (SPME) which is packed with the adsorbent or concentrating medium; a kit for the preparation of a sample comprising the needle for SPME; a method for concentrating a sample; and a method for analyzing an analyte present in a sample.
