[PROBLEMS] To prevent a specimen from being diffused by the improper capacity of tubing. [MEANS FOR SOLVING PROBLEMS] This specimen pretreating device comprises a micro scale or nano scale high-speed liquid chromatograph having a capillary column (2), a probe (1) integrally formed at the tip of the capillary column (2), and an additive feeding flow passage (16). The probe (1) is formed in a multi-tube structure in which a plurality of tubes are disposed on a same axis. The innermost tube is located at the tip of the capillary column (2), and one of the outer tubes is used as an additive supply tube converging an additive solution to an eluent solvent eluted from the capillary column (2) to form liquid drips including the eluent solvent and an additive and the liquid drips are dripped from the tip of the probe (1). The specimen is not diffused since a detector is not present in the flow passage.
