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, ...

Nobel Laureate Linus Pauling, Ph.D., predicted in 1939 that hydrogen bonding would prove to be more significant in the field of biology than any other type of chemical bond. His prediction has been ...

Users often feel a sense of accomplishment when achieving well-defined, isolated spots with a thin-layer chromatography (TLC) plate. Users set up a flash chromatography method, prepare the column, ...
