摘要: An improved method and apparatus for safely introducing sample into a flow stream of supercritical fluid chromatography system is described. The injection improves safety by eliminating the risk injecting high-pressure containing liquids gasses at or near ranges. efficiency significantly shortens time process using check valve placed between fill port on an where injected syringe. After from loop stream, reset to receive subsequent sample. High-pressure mixtures become trapped within when reset. prevents expanding blowing out syringe lines. are directed waste they contained. technique can be applied equally as effective preparatory SFC well analytical systems.
