Thin layer chromatography (TLC), high performance liquid chromatography (HPLC) and mass spectrometry (MS) methods have been developed for the analysis of the antibiotic nybomycin, its derivatives deoxynybomycin and nybomycin acetate, during the fermentation and isolation of nybomycin. Using a ...
Thin-Layer Chromatography: The \"Eyes\" of the Organic Chemist The general aspects and practical applications of thin-layer chromatography (TLC) have been discussed thoroughly in the literature (1,2).TLC methods are su... H Dickson,KW Kittredge,AM Sarquis - 《Journal of Chemical Education》 ...
The main objective of this chapter is to encapsulate the applications of thin-layer chromatography (TLC) and high-performance thin-layer chromatography (HPTLC) as used in the analysis of compounds of pharmaceutical importance. The chapter discusses the advantages of using TLC or HPTLC for biomedical...
Thin Layer Chromatography of Pesticides-A Review of Recent Techniques and ApplicationsRecent advances in the techniques and applications of TLC for the separation, detection, and quantitative determination of pesticides are reviewed. Analyses of a variety of samples for residues of pesticides of various ...

pretreatment. Most peaks were identified by gas chromatography—mass spectrometry. The presence of methane and ethylene sulphide amongClostridiumvolatiles is confirmed and 3-methyl-1-butene, 2-methyl-2-butene, dimethyl trisulphide and S-methyl thioacetate are reported for the first time in...
The limited capability of the solvation parameter model to describe retention for silica gel layers and columns is possibly due to problems in separating o
The obtained filtrate was then evaporated to dryness and separated through silica gel column chromatography (DCM/MeOH=40:1) to give a second side product as white powdery solids (0.63 g, yield 34.2%). 1H NMR (400 MHz, DMSO-d6, ppm) δ 7.36 (s, 2H), 4.89 (s, 2H), 3.41 (s, ...
It is apparent from the published literature that thin-layer chromatography with flame ionization detection TLC-FID is used most extensively for the analysis of simple and complex lipids, especially in biology, in medicine and in the field of vegetable fats and oils. In addition, analyses of phar...
The column chromatography eluate fractions were assessed with thin layer chromatography (TLC) and HPLC coupled to hybrid quadrupole-time of flight analyzer (Q-TOF). For TLC, eluate fractions of 5 μL were spotted on silica gel plates (TLC 60 F254, Merck, Poland). The chromatograms were deve...
