導入装置。 A sample for liquid chromatography that is equipped with a column-side flow path that sends the mobile phase to the column by a liquid feeding means, a separate flow path filled with sample liquid, and a flow path switching device that connects and disconnects these two flow paths. In the introduction device, the separate flow path is composed of two or more types of pipes with different inner diameters, and when the column side flow path and the separate flow path are connected, the two or more types of pipes with different inner diameters are arranged on the upstream side of the mobile phase. A sample introduction device for a liquid chromatograph, characterized in that the sample introduction device is arranged in descending order of inner diameter.
