ABSTRACT:
A high pressure valve for control of the injection of a sample into an analyzer system such as an amino acid analyzer with liquid column chromatography. The valve is designed in such a manner that no rinse solution that is used to cleanse the system after the injection of a particular sample will enter the liquid column. The valve operates in two positions and requires a minimum of movement between the two positions. In one position the valve allows for the injection of the sample into the liquid column. In the second position the valve allows for the entry of only a buffer solution into the liquid column and blocks the entry of any rinse solution that may flow through the system for cleansing after the injection of the sample. No residual rinse solution is allowed to remain within the valve prior to injection of either a sample or a buffer material into the liquid column.
