Apply to the plate 10 ¦Ìl of test solution (a) and 5 ¦Ìl each of test solution (b), reference solution (a), reference solution (b) and reference solution (c).Develop over a path of 10 cm using a mixture of 15 volumes of glacial acetic acid R, 25 volumes of water R and 60 volumes of butanol R. Allow the plate to dry in air.Spray the plate with a 5 g/l solution of dimethylaminobenzaldehyde R in a mixture of 1 volume of hydrochloric acid R and 3 volumes of methanol R. Dry the plate in a current of hot air.Examine in daylight after 30 min.
