Chromatography has developed into one of the principle methods of analysis of oleochemicals. Gas chromatography has been used extensively for the analysis of long-chain fatty acids as well as for the analysis of triglycerides and plant sterols. In recent years, high pressure liquid chromatography (...

The mobile phase is one of two phases associated with chromatography. During the mobile phase in chromatography, the analyte, carried by the eluent, is actively added to the chromatography column. The second phase is known as the stationary, or immobilized, phase. Thestationary phasein chromatograp...
Chromatography, technique for separating the components, or solutes, of a mixture on the basis of the relative amounts of each solute distributed between a moving fluid stream, called the mobile phase, and a contiguous stationary phase. Learn more about
An analytic technique in general use is gas chromatography, which separates the different components of a gaseous mixture by passing the mixture through a long, narrow column of absorbent but porous material. The different gases interact differently with this absorbent material and pass through the ...

in a column made up of a series of vaporization chambers stacked on top of one another. By the early 19th century large-scalecontinuousstills, very similar to those used in the industry today, were operating in France and England. In 1831 the Irishman Aeneas Coffey designed such a still, ...
Molecular sieve column chromatography was used to determine the amount of type I and III collagen synthesized by normal dermis and keloid biopsies and fibroblasts derived from these tissues. After incubation with radioactive proline, the collagen was extracted and separated into types I and III and...
