WebbAbstract. A dynamic theory of thin layer chromatography has been worked out. It is a theory of two-dimensional non-ideal and non-equilibrium chromatography. A basic differential equation has been derived and its fundamental solution obtained. It follows from this solution that the concentration of the substance in the chromatographic zone … Webb2 jan. 2024 · TLC plates are generally made of aluminum coated by the stationary phase, and can be cut with scissors. Sometimes, the supporting material is glass and you will need a glass cutter to do the job. Usually, a thin layer chromatography plate is around 5–7 cm high, and a line is drawn around 0.5–1.0 cm from the bottom.
