WebApr 18, 2015 · Developing a Plate A TLC plate can be developed in a beaker or closed jar (see picture below). Place a small amount of solvent (= mobile phase) in the container. The solvent level has to be below the starting line of the TLC, otherwise the spots will dissolve away. The lower edge of the plate is then dipped in a solvent. WebThe R f-value is dependent on both the compound and the solvent used for development. If we analyze two compounds and they give the same R f-value with the same solvent system, the two compounds are most likely identical. The apparatus for doing a TLC-experiment is very simple. We need a developing chamber where the mobile phase is kept. WebDevelopment. The development chamber is a small screw-capped jar with a 5.5 cm filter paper placed into it to ensure that the atmosphere is saturated with vapor. Each run is relatively brief so please use only one ethyl acetate development chamber. Otherwise there may not be enough for everyone. incontinence boxer briefs washable for women
