Presents theoretical and practical aspects of the most recent advances in countercurrent chromatography, including pH-zone-refining countercurrent chromatography. Examines the use of countercurrent chromatography for the measurement of octanol/water partition coefficients. Describes separation of alkaloids and other pharmacologically active substances from plants. Discusses optimization of solvent systems and reviews the purification of peptides, lipoproteins, and commercial dyes. Includes information on multilayer coil and cross axis countercurrent chromatography and presents theoretical models for comparison and optimization.In the manual measurement, dilution of concentrated solutions becomes a main source of error, resulting in an irregular ... the pH of the fraction as measured manually with a pH meter (Accumet 1001, Fisher Scientific Co., Fair Lawn, PA).
