PURPOSE:To prevent an influence caused by gas, by injecting a sample which has reached a three way joint, into a capillary tube, in a state that it is sandwiched by a solvent, and discharging the gas which has been generated in a waste liquid tube, together with the solvent, in a process of an analysis, to which a high voltage is applied. CONSTITUTION:When a switch 12 is turned off, a solvent consisting of a buffer solution and a micell is made to flow into a three way joint 10 by a head pressure H. Subsequently, when a sample is made to flow into a piping 9 from a sample valve S, it is sandwiched (band B) by the solvent, gets on a flow of the solvent and moves, and when the band B reaches an opening end of a capillary tube 1, a part of the sample is divided by the head pressure H, and injected into the tube 1. Next, after the band B has passed through the opening end of the tube 1, the switch 12 is turned on, and when a high voltage is applied across the tube 1, the sample is separated in the tube 1, and a chromatogram corresponding to a solubilization rate of the sample is detected 6. In this regard, in a process of an analysis, an oxygen gas is generated in a part of an electrode 11 which serves as a waste liquid tube, as well, but the generated gas is discharged to the outside of the device by the solvent which is made to flow continuously. |
