Abstract

A sample delivery system for liquid chromatography is provided. The sample delivery system includes: a sample receptacle; a sample aspiration cannula for aspirating a sample located in the sample receptacle, the sample aspiration cannula being directed using a drive in a direction towards the sample receptacle so that a tip at a distal end of the sample aspiration cannula is immersed in the sample; and a guide element for the sample aspiration cannula provided above the sample receptacle, the guide element being designed as a washing device. The sample aspiration cannula can be retracted using the drive at least so far from the sample receptacle such that the distal end of the sample aspiration cannula may be cleaned in the washing device.
