Automatically actuated parallel sample injector valve

摘要

A sample injector valve capable of introducing multiple samples of material into multiple liquid or gas streams is provided. Such a valve is particularly useful for injecting multiple samples under pressure into a combinatorial chemistry system with moving streams of fluid, such as a parallel pressure reactor or a rapid flow analysis system using multi-channel or parallel chromatography and related techniques. The valve is further capable of functioning on a small scale with automatic sampling equipment.
