Countercurrent chromatography - Wikiwand
Countercurrent chromatography (CCC, also counter-current chromatography) is a form of liquid–liquid chromatography that uses a liquid stationary phase that is held in place by inertia of the molecules composing the stationary phase accelerating toward the center of a centrifuge due to … See more The predecessor of modern countercurrent chromatography theory and practice was countercurrent distribution (CCD). The theory of CCD was described in the 1930s by Randall and Longtin. Archer Martin See more Droplet countercurrent chromatography (DCCC) was introduced in 1970 by Tanimura, Pisano, Ito, and Bowman. DCCC uses only … See more Hydrostatic CCC or centrifugal partition chromatography (CPC) was invented in the 1980s by the Japanese company Sanki Engineering Ltd, … See more Countercurrent chromatography and related liquid-liquid separation techniques have been used on both industrial and laboratory scale to … See more Standard column chromatography consists of a solid stationary phase and a liquid mobile phase, while gas chromatography (GC) uses a solid … See more The modern era of CCC began with the development of the planetary centrifuge by Dr. Yoichiro Ito which was first introduced in 1966 as a closed … See more The aforementioned hydrodynamic and hydrostatic instruments may be employed in a variety of ways, or modes of operation, in order to address the particular separation needs of the scientist. Many modes of operation have been devised to … See more WebOct 25, 2024 · In this respect, HSCCC can be described as a continuous solvent extraction technique where the mobile mixes with the immiscible stationary phase before flowing to the next separation stage, resulting in a net counter-current flow. 95酒精能消毒吗

WebHigh speed counter current chromatography (HSCCC) utilizes a liquid stationary-phase and, hence, does not suffer from irretrievable adsorption associated with conventional chromatography procedures. It is a good alternative for such techniques because of its speedier and economically viable separation, ease of scaling-up, ability for coupling ... WebApr 18, 2012 · Countercurrent chromatography (CCC) is a preparative purification technique working with biphasic liquid systems. One phase of the liquid system is selected to be the mobile phase, the other phase is the stationary phase, held still by centrifugal fields. Aqueous two-phase systems (ATPS) have demonstrated their use in biological … WebOct 3, 2024 · Abstract.
