SOLID PHASE EXTRACTION DEVICE AND VISCOSITY MEASUREMENT DEVICE

摘要

A solid-phase extraction apparatus capable of carrying out highly accurate solid-phase extraction by automatically controlling liquid-permeation speeds in an adsorbing step, a cleaning step, and an eluting step of the solid-phase extraction in order to improve the accuracy of the collection rate of a measurement component(s) also in measurement of each of sample solutions respectively having different viscosities and to ensure a certain processing ability. The solid-phase extraction apparatus includes a sample dispensing unit 5 that dispenses a sample solution 1, a solid-phase extraction unit 6 that carries out a solid-phase extraction process of applying a pressure to the sample solution 1 dispensed by the sample dispensing unit 5 and extracting the measurement component from the sample solution 1, and a converting unit that measures the viscosity of the sample solution 1 and determines the pressure to be applied to a solid-phase extraction cartridge based on the information of the measured viscosity of the sample solution 1.
