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 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...
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 کاملDetermination of 2-phenylethanol in Rose Water Using Dispersive Liquid-Liquid Microextraction with Gas Chromatography Flame Ionization Detection
A simple and rapid microextraction procedure based on dispersive liquid-liquid microextraction (DLLME) coupled with gas chromatography-flame ionization detection (GC-FID) was developed for the extraction and analysis of 2-phenylethanol in rose water sample. In the proposed approach, carbon tetrachloride and ethanol were used as extraction and dispersive solvents, respectively. Some important pa...
