The invention relates to cartridges for thin layer chromatography (TLC) which hermetically seal the TLC mobile phase during loading, performance of the TLC process, and analysis of the chromatogram. It further relates to associated methods of use—for example for detecting or quantifying an analyte ...
A simplified method for rapid determination of porphyrins by thin-layer chromatography.T Okuda, H Nakajima, K Yatsuki, M Amano, G UmedaAbstract Free porphyrins, especially copro-, uro-, and protoporphyrin, were successfully separated by talc thin-layer chromatography (TLC), and were ...

·mL -1.TLC method:the R f value for levodropropizine and benzopizine were 0.62 and 0.46 respectively with a detection limit of 15μg·mL -1.Conclusion:The related substance in levodropropizine can be tested by RP-HPLC or TLC method,but the former is more sensitve and the latter is...
Previously, we established a high-performance liquid chromatography (HPLC) method for determining these three toxic Aconitum alkaloids [5]. By comparing their peak areas, we found that benzoylmesaconine (BMA, Figure 1), one of the benzoylaconines, was more abundant than the other two alkaloids...
The TLC method was reliable for DON evaluation, with a coefficient of variation of less than 10%. High-performance liquid chromatography of lot 2 samples confirmed the presence of DON in all samples identified DON-positive by the TLC technique. Of the 48 wheat flour samples in lots 1 and 2...
The "separation" of analytes resembles normal-phase chromatography, for example, TLC. This method provides a fast, cheap, and simple technique to resolve the NMR spectra of complex mixtures.关键词: Enantioselective synthesis beta-Lactams Azetidin 2 ones Reduction Staudinger reaction ...
The [ 13C]palmitate isotope enrichment measured using direct method was significantly higher than that observed with the BF 3/MeOH-TLC method. The present method provided accurate and precise measures of concentration as well as enrichment when analyzed with gas chromatography combustion-isotope ratio...
