    摘要: This invention relates to an analytical method and an apparatus utilizing a SPE cartridge, which can realize enhanced accuracy and workability in the analysis of trace substances, such as residual pesticides, can clean the inside of piping, needle valves etc, can eliminate the influence on the analysis and can conduct these operations automatically. In the analytical method and apparatus utilizing a SPE cartridge, analytes previously adsorbed to a SPE cartridge is eluted with a solvent from a liquid feed pump. The eluate was injected into a storage chamber in a gas chromatograph through a needle inserted into an injection port in the storage chamber. The needle is pulled up from the injection port, and the inside of the needle is washed with a solvent fed from the liquid feed pump. The wash liquid is discarded, and the analysis of organic compounds as analytes in an subject sample is carried out.

    摘要: An inflow side frit (3), a stationary phase filler (4), and an outflow side frit (5) are installed in a cylindrical cartridge body (1A) from the upper side, a stopper part (1f) supporting the outflow side frit is formed at the inner surface bottom end of the cartridge body (1A), and a fitting part capable of holding the inserted state of the lower end of the other cartridge body (1A) inserted from the upper end of the cartridge body (1A) to a specified position is formed on the cartridge body (1A). The fitting part comprises an inside tapered surface (1g) formed on the inner surface of the cartridge body (1A) on the inserted side and having a diameter increased toward the upper side and an outside tapered surface formed on the outer surface of the cartridge body on the insert side and having a diameter increased toward the upper side.
