Estimation of Polymer Solubility Parameter by Gas-Liquid Partition Chromatography

Gas-liquid partition chromatography: the separation and micro-estimation of ammonia and the methylamines.

Determination of the Solubility Parameter of Soybean Oil by Inverse Gas Chromatography

The solubility parameter ofsoybean oil, 62, has been determined by the technique of inverse gas chromatography (IGC). Using soybean oil as the stationary phase, solute retention volumes were precisely determined as a function of temperature using 22 solute probes of varying solubility parameter (6]). Solvent (oil)-solute interaction parameters, X, were also calculated from the solute retention ...

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 ...

Microbiol. 13:22-27. 1965.-Five gas chromatographic liquid phases (25% Carbowax 20M plus 4% H3PO4, 17.5% dioctyl sebacate plus 7.5% sebacic acid, 17.5% dioctyl sebacate plus 7.5% docosanoic acid, 5% Tween 80, and 20% LAC29...

Hippurate Hydrolysis by Gas-Liquid Chromatography

A rapid gas-liquid chromatographic procedure was developed to determine hippurate hydrolysis by microorganisms. Bacterial cells were inoculated into 0.4 ml of 1% sodium hippurate and incubated for 2 h at 37°C. Cells were removed by centrifugation, and the benzoate released by enzyme activity was converted to methyl benzoate and analyzed by gas-liquid chromatography. This procedure is sensitive,...
