Method and apparatus for delivering a sample to multiple analytical instruments

摘要

A method and equipment for making a chemical analysis of a sample enables multiple analyses to be conducted simultaneously. The system includes a number of injection valves connected in series to a sample inlet line. Each injection valve is connected in a parallel to a separate detection unit. Each injection valve is connected to a pressurized source such as a solvent pump. This equipment includes a sample preparation unit which injects the sample to flow through each of the valves. Each of the valves will retain a portion of the sample in a sample chamber. Each valve will rotate to an injecting position wherein the pressurized solvent pushes the sample into the separate detection units.
