1Countercurrent chromatography — (CCC) or partition chromatography is a category of chromatography techniques;[1] laboratory techniques for the separation of mixtures, in this case liquid liquid mixtures. Contents 1 Chromatography 2 Techniques …
2Countercurrent exchange — Counter heat current exchange: Note the gradually declining differential and that the once hot and cold streams exit at the reversed temperature difference; the hotter entering stream becomes the exiting cooler stream and vice versa.… …
3Countercurrent multiplication — A countercurrent multiplier system is a mechanism that expends energy to create a concentration gradient. It is found widely in nature and especially in mamalian organs. For example, it can refer to the process underlying the process of urine… …
4countercurrent distribution — ▪ chemistry in chemistry, a multistage solvent extraction process, one of many separation methods that can be employed in chemical analysis. Substances are separated by this method on the basis of their different solubilities in two… …
5Multicolumn countercurrent solvent gradient purification — (MCSGP) is a form of chromatography that is used to separate or purify biomolecules from complex mixtures. It was developed at the Swiss Federal Institute of Technology Zürich by Aumann and Morbidelli.[1] The process consists of three to six… …
6Sulfite process — The sulfite process produces wood pulp which is almost pure cellulose fibers by using various salts of sulfurous acid to extract the lignin from wood chips in large pressure vessels called digesters. The salts used in the pulping process are… …
