TLC is carried out on a 5 x 20 cm silica gel precoated plate (Merck) with a solvent system of pyridine-ethylacetate- acetic acid-water (75 25 15 30), tert-butanol-acetic acid-water (2 1 1) or n- butanol-acetic acid-water (60 15 25) (11). Similarly, the solvent system composed of butanol:acetic acid:water was not further explored because of the need to neutralize the CPC fractions with . 1uL of aminoacid solution in water (5mg/mL; 3mg Na2CO3 added for Cystine, Phenylalanine and Tyrosine) was applied (about 3mm spot was formed).This means each spot contained 5ug (65 nmols to 25 nmols) of an aminoacid. The role of certain details important in the technique of TLC are layer thickness and homogeneity, degree of layer activation, solvent quality and aging of solvent mixtures, design of separation chamber and layer location, length of run of the solvent and distance from the immersion level to the origin of the chromatogram, technique of sample ap. THEORY Chromatography is a physicochemical method for separation of A "phase diagram" of the type shown is required for all commonly used three-component paper chromatographic solvent mixtures to facilitate the design of one-phase solvents for particular problems. acetate : formic acid : acetic acid :water, 100 : 11 : 11 : 27, and .
