Isolation edit Since different compounds will travel distance the stationary phase chromatography can be used isolate components of mixture for further analysis. For Ccoated plates the order is reverse. As consequence the less polar compound moves higher up plate resulting Rf value. Kormos C. This method much more sensitive than the others and can be used to detect extremely small amount of compound provided that carries radioactive atom

The TLC plate is then placed in chamber so that spot of sample do not touch surface eluent and lid closed. WileyBlackwell. the reaction is complete if any product has appeared and how many products generated although this might be underestimated due to coelution.

A small amount of an appropriate solvent eluent is poured into glass beaker or any other suitable transparent container separation chamber depth less than centimeter. This ratio called the retardation factor Rf. M.

By changing the solvent or perhaps using mixture separation of components measured Rf value can be adjusted. An eluotropic series can be used as guide in selecting mobile phase. pp
