Some reagents can be impregnated into the layer before spotting of samples if the selectivity of the separation is not affected. Detection takes place only upon heating after development. This method has been used for the detection of lipids as blue spots on a yellow background on silica gel layers preimpregnated with phosphomolybdic acid. A few detection reagents (HCl, sulfuryl chloride, iodine) can be transferred uniformly to the layer as vapors in a closed chamber rather than as solutions. 

In addition to iodine, other detection reagents (e.g., bromine, chlorine, formaldehyde, ammonia, diethylamine, HCl, sulfuryl chloride, sulfur dioxide, oxides of nitrogen, and ammonium bicarbonate) (see Section 11) can be applied as vapors.
