Abstract

The sample injection valve for high-performance liquid chromatography (HPLC) devices comprises a stator with inlets for the sample and the mobile phase, outlets leading to the chromatography column and to a waste collector, as well as connections for both ends of a sample loop. Its rotor has the customary connection channels. An additional washing liquid inlet (7) opens into the connecting channel (9) that, in one valve position, connects the sample inlet (1) to the outlet (2) leading to the waste collector. This enables the sample inlet and the pipette or syringe located therein to be rinsed.
