Chromatography method and apparatus

摘要

Method and apparatus for effecting thin-layer chromatographic (TLC) analysis including a chamber open at the bottom and adapted to retain a strip of chromatographic material. The chamber is moved in time relation alternatively into and out of a first container of a solution of the material being analyzed to effect alternative irrigation and drying of the strip so that a high resolution of solutes is accomplished on the strip. A secondary reservoir of the solution in a closed container is connected to the first container so as to maintain the solution level in the first container constant.
