摘要： A capillary made of plastics material that is suited for use in capillary electrophoresis. The capillary has its inner surface chemically modified for the generation of properties different from those of the original plastic capillary material. In the process of producing such capillaries, a premanufactured capillary is treated with a chemical reagent which generates functional groups directly on the capillary surface or generates attachment sites, on the capillary surface to which functional groups are later bonded.

摘要： A method for recovering at least one unsaturated fatty acid having sixteen or more carbon atoms and/or at least one compound of such a fatty acid from a mixture derived from vegetable, animal or marine sources is provided. Fatty acids and/or fatty acid compounds of the mixture, in free acid or esterified form, are passed into a mobile phase of liquid carbon dioxide in a column over a stationary phase. The stationary phase contains a support and a material bound to the support which contains at least one free electron pair and/or multiple bond. After eluting any saturated fatty acid or fatty acid compound of the same number of carbon atoms from the column, the unsaturated fatty acid and/or fatty acid compound is recovered in pure chemical form or as an enriched mixture.

摘要： The invention relates to a method for obtaining fatty acid esters and fatty acids, preferably unsaturated fatty acid ethyl esters, from biological sources by continuous, combined in-situ extraction, reaction and chromatography. The invention is characterized in that simultaneously and in the same location, in the presence of a compressed gas and an 0.5-5 % stream of lower alcohols as modifiers and in the presence of an inert catalyst, the fatty acids are fully transesterified from their native fatty acid sources, which are selectively desorbed and eluated in the conditions specified above.

摘要： A process for obtaining pharmacologically active compounds from complex mixtures of substances Free organic acids, hydroxy acids, fatty alcohols, sugars and hydroxy-substituted steroids are obtained from complex mixtures of substances by mixing the material to be extracted with a polar solvent, drying the resulting mixture, subsequently silylating, esterifying or acylating, and extracting the resulting material with a supercritical fluid under a pressure of more than 200 bar.
