Paper chromatography is a useful technique because it is relatively quick and requires only small quantities of material. Separations in paper chromatography involve the principle of partition. In paper chromatography, substances are distributed between a stationary phase and a mobile phase.
Planar chromatography is a separation technique in which the stationary phase is present as or on a plane. The plane can be a paper, serving as such or impregnated by a substance as the stationary bed (paper chromatography) or a layer of solid particles spread on a support such as a glass plate (thin-layer chromatography).
The Journal of Chromatography B is a peer-reviewed scientific journal publishing research papers in analytical chemistry, with a focus on chromatography techniques and methods in the biological and life sciences.
The introduction of paper chromatography was an important analytical technique which gave rise to thin-layer chromatography. [13] Finally, gas-liquid chromatography, a fundamental technique in modern analytical chemistry, was described by Martin with coauthors A. T. James and G. Howard Smith in 1952. [14]
Electrochromatography is a chemical separation technique in analytical chemistry, biochemistry and molecular biology used to resolve and separate mostly large biomolecules such as proteins. It is a combination of size exclusion chromatography (gel filtration chromatography) and gel electrophoresis. These separation mechanisms operate ...
Archer Martin shared the 1952 Nobel Prize in Chemistry for the invention of partition chromatography with Richard Synge. [10] [11]Archer Martin's 1954 paper with A. T. James, "Gas-Liquid Chromatography: A Technique for the Analysis and Identification of Volatile Materials” reported the discovery of gas-liquid chromatography.
Chromatography is a physical method of separation that distributes the components you want to separate between two phases, one stationary (stationary phase), the other (the mobile phase) moving in a definite direction. Cold ethanol precipitation, developed by Cohn in 1946, manipulates pH, ionic strength, ethanol concentration and temperature to ...
The major difference between Journal of Chromatography A and Journal of Chromatography B is the focus being on preparative chromatography instead of analytical chromatography. The split of the Journal of Chromatography into two journals occurred in late 1993, with volume 652 being the first for Journal of Chromatography A .
