Abstract:
1. A pretreatment apparatus comprising: a solid-phase extraction cartridge for separating a specific component from a sample solution; a cartridge holding container for housing the solid phase extraction cartridge; a cartridge transfer means for holding a plurality of the cartridge holding containers; a sample solution injection mechanism for injecting the sample solution into a selected one of said plurality of cartridge holding containers; a reagent injection mechanism for injecting a reagent into said selected one of said plurality of cartridge holding containers; a pressurizing section for applying pressure to said selected one of the plurality of cartridge holding containers; a pressure holding section for holding the pressure applied to said selected one of the plurality of cartridge holding containers from the pressurizing section, an extraction solution receiver mechanism for receipt of the specific component separated from the sample solution by said solid-phase extraction cartridge; whereby said sample solution injection mechanism, said reagent injection mechanism and said pressurizing section are arranged with respect to said cartridge holding means so that said sample solution injection mechanism, said reagent injection mechanism and said pressurizing section can process and can operate with at least two of said plurality of cartridge holding containers being held by said cartridge transfer means, and a control section, including a controller configured for simultaneously controlling all parts of the pretreatment apparatus automatically and including controlling at least two of a change of a position of the cartridge transfer means to change a relative position between said cartridge transfer means and said pressurizing section, to change a relative position between said cartridge transfer means and said sample solution injection mechanism, to change a relative position between said cartridge transfer means and said reagent injection mechanism, and a relative position between said cartridge transfer means and said extraction solution receiver mechanism, whereby said at least two of said plurality of said cartridge holding containers to be operated and processed can be simultaneously changed, said control section controller further being configured for controlling the operation of the cartridge transfer means, the sample solution injection mechanism, the reagent injection mechanism and the pressurizing section.
