Thin-layer chromatography (TLC) is a chromatography technique that separates components in non-volatile mixtures. [1] It is performed on a TLC plate made up of a non-reactive solid coated with a thin layer of adsorbent material. [2] This is called the stationary phase. [2]
Picture of HPTLC plate to identify different substances within a sample. High-performance thin-layer chromatography (HPTLC) serves as an extension of thin-layer chromatography (TLC), offering robustness, simplicity, speed, and efficiency in the quantitative analysis of compounds. [1]
The theoretical plate concept was also adapted for chromatographic processes by Martin and Synge. [6] The IUPAC's Gold Book provides a definition of the number of theoretical plates in a chromatography column. [7] The same equation applies in chromatography processes as for the packed bed processes, namely:

Planar chromatography is a separation technique in which the stationary phase is present as or on a plane. The plane can be a paper, serving as such or impregnated by a substance as the stationary bed (paper chromatography) or a layer of solid particles spread on a support such as a glass plate (thin-layer chromatography).
A Florida attorney found himself on the wrong side of the justice system after he allegedly smashed a dinner plate on a man’s head during a wedding reception. Mark Roher, a lawyer who ...
True, this meal takes more time and TLC than opening a jar of Ina’s preferred jarred marinara (Rao’s) and warming up frozen meatballs. But after enjoying my first serving, I can verify that ...
In chromatography, the retardation factor (R) is the fraction of an analyte in the mobile phase of a chromatographic system. [1] In planar chromatography in particular, the retardation factor R F is defined as the ratio of the distance traveled by the center of a spot to the distance traveled by the solvent front. [2]
