The following method conditions are suitable for the semi-quantification of (polar lipids) phospholipids and ceramides. Non-polar lipids (MG, DG, TG, Cholesterol, Cholesterol Esters, etc.) elute in the solvent front using these conditions and therefore concentration values obtained are for monitoring only and should not be deemed quantitative with this method.

Most sample vials are made of plastic or glass, and include a separate or attached lid or closure. Sample vials are categorized by material and also by their size or specific purpose. Glass sample vials are categorized by the type of glass used to make them. Type I, Class A glass sample vials are made from low-expansion borosilicate glass.

Jun 3, 2020 · Lipid analysis in mammalian systems have focused on steroids, cholesterol and bile acids, while plants systems focus on phytosterols and phytostanols. Thin layer chromatography–flame ionization (TLC-FID) and GC-MS techniques were initially used to determine ST with the requirement of derivatization (e.g., trimethylsilation and methylation).

In this application note, UPC2 technology is implemented for the analysis of lipid class separation. Method variables influencing the peak integrity and chromatographic separation for a mixture of lipids with different degrees of polarity are explored. The experiments were designed to understand the chromatographic behavior of lipids in a controlled setting using a variety of lipid extracts.
