SOLID PHASE EXTRACTION DEVICE AND VISCOSITY MEASUREMENT DEVICE

摘要

The present invention is a solid phase extraction device capable of performing high-accuracy solid phase extraction by automatically controlling the liquid flow speed in an adsorption step, a cleaning step, and an elution step of the solid phase extraction in order to improve the accuracy of the collection rate of a measurement component and ensure constant treatment capability even in the measurement of respective sample liquids having different viscosities. A solid phase extraction device is provided with a sample dispensing unit (5) which dispenses a sample liquid (1), a solid phase extraction unit (6) which applies pressure to the sample liquid (1) dispensed by the sample dispensing unit (5) and performs solid phase extraction treatment for extracting a measurement component from the sample liquid (1), and a conversion unit (4) which measures the viscosity of the sample liquid (1) and determines the pressure to be applied to a solid phase extraction cartridge on the basis of information relating to the measured viscosity of the sample liquid (1).
