J. Sep. Sci. 30, 964-970 (2007). Multidimensional planar chromatography of a mixture of five groups of pesticides: (1) diuron, isoproturon, and lenacil; (2) monolinuron, propoksur, carbaryl, and simazine; (3) alachlor and dinoseb; (4) trifluralin, tetradifon, p,p´-DDT, and 4,4´-dibromobenzophenone; (5) hexachlorobenzene. The silica gel plate was developed in the first dimension with ethyl acetate – n-heptane 1:3, and then turned by 90°. Portions of the stationary phase were sequentially removed to ensure that the mobile phase of the following developments reaches only the target spots: (2) chloroform – n-heptane 19:1 (4) acetone – n-heptane 1:59, (3) toluene, and (1) ethyl acetate – dichloromethane 1:9. The plate was dried between 5 and 15 min before each development. Detection under UV light at 254nm.
