Use of thin-layer chromatography on silica gel for serum lipid fractionation and measurement in the routine clinical laboratory.
A procedure, appropriate to use in the routine laboratory, is described for thin-layer chromatographic separation of serum lipids on silica gel, followed by molybdate coloring and densitometry. Cholesteryl aniline is used as the internal standard. The procedure is recommended as a screening procedure for presenting graphically the lipid distribution in the serum. Fractions separated and values ...
متن کاملThe fractionation of phosphatidylinositol into molecular species by thin-layer chromatography on silver nitrate-impregnated silica gel.
1. Two methods for the fractionation of phosphatidylinositol into molecular species were developed. In addition to preserving the fatty acid moiety of the molecule, the first method preserves the phosphorus, and the second preserves both the phosphorus and inositol ring. 2. In the first method, phosphatidylinositol was oxidized with periodate and the products reacted with diazomethane. I.r. exa...

Commercial precoated thin-layer chromatography (TLC) and highperformance TLC (HPTLC) plates with spherical or irregular particles have been compared on the basis of theoretical plate number (N), resolution (R), linearity, development time, and limit of sensitivity for analysis of a multicomponent analgesic tablet in the fluorescence quenching mode and analysis of a five-component dye mixture in...

متن کاملThin-Layer (Planar) Chromatography
Synthetic dyes comprise a large group of organic, organic salt and organometallic compounds which number in the thousands. Most individual dyes are assigned colour index (CI) numbers which helps to identify structure and properties as well as identity where a series of names have been used by the manufacturers for the same dye. Pigments are also listed and can be either organic or inorganic in ...
