Improved conditions for gas-liquid chromatography of triglycerides

Improved conditions for gas--liquid chromatography of triglycerides.

Improved conditions for gas-liquid chromatography of triglycerides are reported. Triglycerides of bovine colostrum and rapeseed oil have been analyzed under these conditions.

Separation of triglycerides by gas-liquid chromatography.

The parameters affecting the separation and quantification of triglycerides by gas-liquid chromatography have been investigated with the use of QF-1 and SE-30 as stationary phases and a flame ionization detector. The isothermal characteristics of a wide variety of triglycerides (carbon number 6 to 60) on both columns show that long retention volume is directly proportional to carbon number and ...

Microreactor for methanolysis of triglycerides before gas-liquid chromatography.

A rapid, accurate microtechnique has been developed for gas chromatographic determination of the fatty acid composition of small (2-3 micro l) samples of vegetable oils. This microtechnique combines transesterification and sample injection into a single operation. The fatty acid compositions of soybean, linseed, and safflower oils thus determined are compared with those obtained by the usual tw...

Micro Gas Chromatography for Liquid Petroleum Gas's

For years, microGC analysis has been useful as a powerful tool for the fast and reliable analyses of natural gas and other gaseous matrices; but, it is yet to prove its capabilities for liquid samples. In this paper, we present a unique gasifying system for volatile liquid sample introduction in a microGC. The system has been tested with a wide range of different samples: liquefied gases (ethan...
