Among mixed solvent systems, a water-organic mixture is frequently used, e.g. The presence of a swamp acid also increases the solubility of the water-immiscible solvent for water. Acceptable resolutions were achieved when it was applied for the separation of dipeptides including Leu-Tyr and Val-Tyr by using 1-butanol-acetic acid-water (4:1:5, V/V/V) solvent system. Alternative solvents have been suggested, for example, butanol - acetic acid 5, acetone - water 2 and pyridine - amyl alcohol 6.

The mixture of xylose oligomers was subsequently fractionated by a centrifugal partition chromatography (CPC) with a solvent system of butanol:methanol:water in a 5:1:4 volumetric ratio. Similarly, the solvent system composed of butanol:acetic acid:water was not further explored because of the need to neutralize the CPC fractions with . A new solvent system has been found which, in com- parison with the solvent system butanol - glacial acetic acid - water (BA W), permits a sharper paper chromato- graphic separation of the 3-monoglucosides and the 3,5-diglucosides of the six common an thocyanidins. The influence of T on Sf was not obvious between 20 degrees C and 40 degrees C, lower temperature than 20 degrees C was not suitable for viscous ATPSs. author t j betts .
