This invention makes it possible to easily and quickly derivatize and recover at least one organic compound selected from amino acids, organic acids, and sugars included in a sample to be analyzed, by means of an amino acid, organic acid, and sugar analysis pretreatment device comprising: an ion-exchange unit configured so as to load samples to be analyzed into a solid-phase cartridge S having a strong ion-exchange resin phase, adsorb a prescribed organic compound to the strong ion-exchange resin phase, and then supply a dehydrating solvent to dehydrate the strong ion-exchange resin phase; and a derivatization unit configured so as to supply a prescribed amount of a derivatization reagent to the dehydrated strong ion-exchange resin phase and retain the derivatization reagent for a prescribed period of time, desorb the organic compound adsorbed to the strong ion-exchange resin phase from the strong ion-exchange resin phase and at the same time trimethylsilylate the organic compound, and then supply an extrusion solvent to extrude the desorbed trimethylsilylated organic compound from the solid-phase cartridge S. This invention also makes automation possible. |
