STATIONARY PHASE EXTRACTION CARTRIDGE

摘要

A stationary phase extraction cartridge enabling the fitting of a plurality of stationary phase cartridges to not only minimizing the accumulation of a specimen and a solution but also rapidly obtain a plurality of target components for removing impurities. 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.
