Separation of mono- and diglycerides by gas-liquid chromatography

Journal of Lipid Research, 1969
The parameters affecting the separation and quantification of trimethylsilyl ethers of mono- and diglycerides have been investigated by gas-liquid chromatography with QF-1 and SE-30 as stationary phases and a flame ionization detector.

Transport property predictions for laser resonance chromatography on Rf$^+$ (Z = 104) [PDF]

arXiv
We propose a theoretically designed laser resonance chromatography (LRC) experiment on Rf$^+$ (Z = 104) drifting in He buffer gas. To this end, we first developed a four-level rate equation model that simulates the optical pumping of Rf$^+$ from its ground state, $^2$D$_{3/2}$ (7s$^2$6d$^1$), to the metastable $^4$F$_{3/2}$ (7s$^1$6d$^2$) state via ...

Separation of brain monosialoganglioside molecular species by high-performance liquid chromatography.

Journal of Lipid Research, 1984
A method for the separation of molecular species of brain monosialogangliosides by high-performance liquid chromatography is described. GM4, GM3, GM2, and GM1 were purified from human brain and their individual molecular species were separated on a C18 ...

Measurement of 5,8,11, 14-icosatetraynoic acid in plasma by gas-liquid chromatography

Journal of Lipid Research, 1981
A gas-liquid chromatography-flame ionization detection method is described for measuring plasma levels of eicosatetraynoic acid using eicosatriynoic acid as an internal standard. The technique is simple, rapid, and reproducible. Eicosatetraynoic acid and

Studies of canine adrenal polyenoic acids: locating double bonds by periodate-permanganate oxidation and gas-liquid chromatography*

Journal of Lipid Research, 1962
An improved micromethod has been developed for the location of double bonds in some naturally occurring polyenoic acids by oxidative cleavage of olefinic bonds with a mixture of periodate and permanganate (von Rudloff's oxidant) and analysis of the ...
