Thin layer chromatography (TLC) using staining reagents is a superior method for analyzing organic compounds without chromophores. It is fast, versatile and sometimes the only viable method. We have investigated quantitative TLC using staining reagents, in combination with modern image analysis software....
A negative matrix effect (-28%) of the wheat flour was verified, with suppression of the chromatographic signal of DON, and 80.2-105.4% recovery. The TLC method was reliable for DON evaluation, with a coefficient of variation of less than 10%. High-performance liquid chromatography of lot 2...
29,30. Out of 48,218 medicine analyses included in an authoritative WHO review1, 20,010 had been carried out using the GPHF Minilab. The Minilab relies especially on thin-layer chromatography (TLC), a well-established, low-cost chromatographic technique...
Milkfat is a complex mixture of many diverse FA, some of which have demonstrated health benefits including anticancer properties. Attempts are under way to enrich milkfats with long-chain n3 PUFA and CLA. It has been recommended that the analysis of these milkfats requires gas chromatography (GC...
Forensic Application of an Automated Drug-Profiling System The rapid emergency drug identification (REMEDi鈩 ) system is an automated drug-profiling system that employs high-performance liquid chromatography with a ... KS Kalasinsky,T Schaefer,SR Binder - 《Journal of Analytical Toxicology》 被引量...
To establish the local quality standard for Dendrobii devoniani caulis from Longling,Yunnan,the pharmacognostic characteristics microscopic characteristics and TLC identification were developed. Sulfuric acid-phenol method was used to determine the content of polysaccharide. An HPLC method was adopted to ...
The toxicological significance of paraquat concentrations in paraquat poisonings was evaluated by means of multivariate analysis methods. Paraquat could be determined by a newly developed procedure, which involved thin-layer chromatography with flame ionization detector (TLC-FID) and solid-phase extraction ...
At first, an aqueous solution of sodium borohydride (NaBH4, 3 mL, 8–10 mg/mL) was passed slowly through support over 10 min for converting [18F]15 to [18F]16, and > 85% radiochemical conversion (RCC) based on radio-thin layer chromatography (TLC) was noticed (...
