Dynamics 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 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 کاملBarbiturate detection using thin-layer chromatography.
NilEDICATIONS are one of the leading causes of fatal and nonfatal poisonings. Of all medications, salicylates (in children) and barbiturates (in adults) are most frequently involved in these poisonings. When these occur, the physician treating the victim may request a chemical analysis of a blood sample to confirm his clinical impression. A salicylate analysis is simple and rapid (1). However, ...
متن کاملBioautography detection in thin-layer chromatography.
Bioautography is a microbial detection method hyphenated with planar chromatography techniques. It is based mainly on antimicrobial or antifungal properties of analyzed substances. The review discusses three versions of bioautography, i.e. contact, immersion and direct bioautography. The more concern is given to the last one. Many applications are quoted, not only for testing various groups of ...
متن کاملDetection of Aflatoxins in Peanut Oils Marketed in Peshawar, Pakistan Using Thin Layer Chromatography
Background: Aflatoxins (AFs) are natural toxins produced by fungus belonging to genus Aspergillus. These toxins are the secondary metabolites, which may cause teratogenic, mutagenic, and carcinogenic effects due to contamination of food. Peanut is an economically important crop, grown in many parts of the world. The main aim of this survey was to detect AFs in peanut oils marketed in Peshawar, ...
