Improvement in Resolution of Low Melting Point Triglyceride Molecular Species on Chilled Column Isocratic Liquid Chromatography

Column Liquid Chromatography

High−Speed Analyses using Rapid Resolution Liquid Chromatography on ZORBAX column packed 1.8 μm Particles

Over the years, separation resolution and reduction of analysis time has continually improved in High Performance Liquid Chromatography (HPLC). For further improvement, column efficiency must be increased. The relationship among separation efficiency, the mobile phase linear velocity and particle size was investigated in detail in the early 1970 s [1]. This and other systematic investigations h...

Separation of galactolipid molecular species by high-performance liquid chromatography.

A technique for the separation, detection, and quantification of molecular species of monogalactosyldiglyceride and digalactosyldiglyceride is described. Use of the technique to analyze the molecular species composition of the galactolipids isolated from Dunaliella salina chloroplasts is presented. The results indicate that the respective compositions of the two lipids are quite different. This...
