Abstract
Self-washing injection apparatus [ ] for liquid chromatography injection valves utilizes an interior chamber [ ] with a penetrable seal [ ] at the top end of the chamber and a needle sleeve seal [ ] at the bottom end of the interior chamber. A wash port [ ] in the body [ ] of the apparatus connects one or more sources of wash fluid to the interior chamber between the penetrable seal and the sleeve seal. The apparatus provides a simple and effective means to aspirate or pump wash fluids from one or more wash fluid reservoirs through the apparatus, the injection port of the injection valve, and associated components.
