Summary:A sample pre-compression valve for liquid chromatography applications is described. The valve enables a sample pre-compression while the solvent pump continues to conduct solvent to the chromatography column. Furthermore, the sample pre-compression valve includes an INJECT position, a LOAD position and a PUMP PURGE position, in which all connecting grooves of the valve are flushed with liquid. A use of the sample pre-compression valve is described as part of a sampler for liquid chromatography applications.
