Abstract
A biological sample preprocessing apparatus includes solid-phase extraction cartridges which purify/concentrate specific constituents of a biological sample, cartridge holders which hold one of the solid-phase extraction cartridges, a cartridge transport that carries the cartridge holders along a continuous track surface, a sample probe that discharges the biological sample into the solid-phase extraction cartridge held in the cartridge holders, a water-based solvent probe that discharges a water-based solvent into the solid-phase extraction cartridge held in the cartridge holder, an organic solvent probe that discharges an organic solvent into the solid-phase extraction cartridge held in the cartridge holder, a pressure loader that applies an air pressure load to the solid-phase extraction cartridge held in the cartridge holder, and a control unit that controls operation of the cartridge transport, the sample probe, the solvent probes, and the pressure loader, wherein sample addition and solvent addition alternate with pressure loading.
