Elution Countercurrent Distribution

Analytical Biochemistry, 1987
The single withdrawal technique, here called elution countercurrent distribution, was applied for the first time on aqueous two-phase systems. The modifications necessary for elution countercurrent distribution of a thin-layer countercurrent distribution apparatus are described.

Thin-layer countercurrent distribution

Analytical Biochemistry, 1965
Abstract An apparatus for countercurrent distribution with aqueous polymer two-phase systems is described. The settling time is reduced by using thin layers of the two phases. An experiment with sulfuric acid shows a good agreement between the experimental and the theoretical countercurrent distribution diagrams. A separation of two microorganisms by

Countercurrent Distribution in Protein Chemistry

1956
Publisher Summary The chapter discusses the countercurrent distribution in protein chemistry. The chapter presents the basic principles of countercurrent distribution, including the distribution law of Nernst and Partition Coefficient, multiple distribution, calculation of the fundamental process, and distribution curves.

Modern Countercurrent Distribution

Separation and Purification Methods, 1975
Abstract Interest in liquid-liquid extraction continues to grow as evidenced by such divergent applications as industrial waste water treatment1,2 cleanup for pesticide residue analysis3, and resolution of optical isomers.4 This activity results from increased understanding of the chemistry of solvent extraction which is leading to the design of ...

Countercurrent distribution of poliovirus type 1

Virology, 1963
Abstract Differences in the countercurrent distribution pattern in an aqueous polymer phase system are demonstrated for various strains of poliovirus type 1. The attenuated strains L Sc 2 ab and Baylor Att.-1 have partition coefficients of 0.2–0.4 whereas the CHAT strains and a virulent strain have partition coefficients of ≈4.

Circular countercurrent-distribution behavioral genetic maze

Journal of Heredity, 1977
An inexpensive, easily constructed apparatus for mass screening of taxes of small animals with a rapid and accurate assignment of individual behavior scores has been described that should be of utility in hastening a behavioral geneticist's chores and allow him to handle more populations with fewer mazes.
