Abstract

A specimen pretreating device which includes a micro scale or nano scale high-performance liquid chromatograph having a capillary column (), a probe () integrally formed at the tip of the capillary column (), and an additive feeding flow passage (). The probe () is formed in a multi-tube structure in which a plurality of tubes are disposed on the same axis. The innermost tube is located at the tip of the capillary column (), 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 () to form liquid drops including the eluent solvent and an additive, and the liquid drops are released from the tip of the probe (). The specimen is not diffused since a detector is not present in the flow passage.
