Analysis of Heavy Oils by Thin-Layer Chromatography with Flame Ionization Detection†
Several rapid methods for compositional analysis of heavy oils by thin layer chromatography with flame ionization detection (FID-TLC) were investigated. Separating into four fractions, Saturates, Aromatics, Resins, and Asphalten, SARA analysis of heavy oils could be accurately performed by three stage development using n-hexane, toluene, and tetrahydrofuran. Detailed hydrocarbon type analysis o...
متن کاملDynamics of bitumen fractions by thin-layer chromatography/flame ionization detection
Thin-layer chromatography/flame ionization detection (TLC/FID) allows for the fractionation of bitumen into four fractions, namely, the saturates, the aromatics, the resins A and the resins B (SARAB). The technique is rapid and economical, but it lack reproducibility. The effect of chromarod aging on reproducibility was investigated along with that of the time between bitumen dissolution and it...
متن کاملAnalysis of Hydrocarbons in a Hydrogen Atmosphere by Gas Chromatography with Flame Ionization
The ionization response of hydrocarbons In a hydrogen-atmosphere flame was compared to that of a normal flame ionization detector used in gas chromatography. Absolute response in the hydrogen-atmosphere flame lonizatlon detector (HAFID) was found to be two orders of magnitude less than that of the normal FID. This reduced response is attributed both to oxidation of hydrocarbons in the precombus...
متن کاملDetermination of amniotic fluid phospholipids by thin-layer chromatography, with use of a hydrogen flame ionization detector.
We describe a new specific method for measuring lecithin, sphingomyelin, and phosphatidylglycerol in amniotic fluid by thin-layer chromatography, with use of a hydrogen flame ionization detector. After extraction and acetone precipitation to isolate surface-active lecithin, the phospholipids are separated on a thin rod of refractory and chemically stable material, having an outer coating of a b...
متن کاملif . Thin Layer Chromatography / Flame Ionization Analysis of Transesterified Vegetable Oils 1
A quantitative method was developed for analyzing mixtures containing fatty esters and tri(TG), di(DG) and monoglycerides (MG) obtained by the transesterification of vegetable oils. Analyses were performed by thin layer chromatography (TLC)/flame ionization detection (FlO) with an latroscan TH-10 instrument. Stearyl alcohol served as an internal standard. From plots of area and weight ratios of...
