A new accurate, precise thin layer chromatographic (TLC densitometric) approach was developed for the simultaneous analysis of ergotamine tartrate (ERG), phenobarbital sodium (PHEN), caffeine ...

Thin-layer chromatography (TLC) was widely used in the 1960s and 1970s for pesticide residue analysis, but only to a limited extent since gas–liquid chromatography (GLC) and high performance liquid ...

THIN-LAYER CHROMATOGRAPHY (TLC) has long been a staple of the organic laboratory, and its silica-on-glass plates are familiar even to undergraduate chemistry majors. But for advanced applications, TLC ...

Chromatography is relied on by many disciplines as a method of separating the components of a mixture. The basic idea of the process is that distinct compounds have different levels of solubility, ...
