A new and simple technique for thin-layer chromatography (TLC) was devised by use of thin-layer stick in place of thin-layer stick in place of thin-layer plate. The glass sticks used were slim glass tubes of 2.5 mm in diameter and 13 cm in length. The separation and identification of 20 common anions were examined on a thin-layer stick of silica gel containing 2% of soluble starch by using 3 kinds of developing solvent. The separation of CNS^-, I^-, Br^-, Cl^-, Fe (CN)^<4->_5,Fe (CN)^<3->_6,ClO^-_3,BrO^-_3,IO^-_3 and NO^-_3 by acetone : H_2O (10 : 1), F^-, NO^-_2,S_2O^<2->_3,SO^2_4,CrO^2_4,PO^<3->_4,AsO^<3->_3 and AsO^<3->_4 by methanol : n-butanol : H_2O (3 : 1 : 1), C_2O^<2->_4 and BO^-_2 by n-butanol saturated with 2N HNO_3 were successfully carried out. Thin-layer sticks developed for anions with respective solvent mixtures were allowed to dry in air and then immersed for a short time in color reagent. The tests yielded gratifying results with respect to the efficiency of detection and to the simplicity of the procedure.
