Quantitative determination of diethylene glycol contamination in pharmaceutical products.
A simple, rapid, and reliable method was developed for the quantitative determination of diethylene glycol (DEG) in pharmaceutical products using capillary gas chromatography with flame ionization detection. The method uses ethylene glycol as internal standard and allows for the separation of propylene glycol and DEG. The assay was linear in a DEG concentration range between 1.0 and 10.00 mg/mL...
متن کاملA Simple Apparatus for Thin-layer Chromatography.
Thin-layer chromatography was introduced by Stahl (1956) and has advantages over paper chromatography in speed, resolution, and smaller sample size. Also, the physical nature of the thin layer allows its treatment, where necessary, with strong acids and alkalis. It has been found possible to construct a satisfactory, cheap, and simple apparatus for the preparation of thin layers on glass carrie...
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, ...

15 صفحه اولChemiluminescence detection of gangliosides by thin-layer chromatography.
We describe a method for the detection of gangliosides on thin-layer chromatography plates using enhanced chemiluminescence. In contrast to previously published colorimetric techniques, the use of chemiluminescence of detect antibody binding to gangliosides has increased sensitivity and simplicity. In addition, the use of chemiluminescence lacks the hazards of radioactivity, and produces a perm...
