Three ways of visualising the molecular components separated during chromatography include shining ( a UV light, white light, different coloured lights, infrared light ) over a ( TLC plate, gas chromatography column, mobile phase ), spraying ( ninhydrin, amino acid molecules, starch, sodium hydrogen carbonate ) on ( amino acid molecules, triglyceride molecules, reducing sugars, non-reducing sugars ), or adding ( iodine crystals, chlorine gas, alkaline solution, copper sulphate ).
