how can tlc be used to identify a compound?
7239
TLC can be used to help determine the number of components in a mixture, the identity of compounds, and the purity of a compound. By observing the appearance of a product or the disappearance of a reactant, it can also be used to monitor the progress of a reaction.

Chromatography Columns. Thin layer chromatography (TLC) can be used to separate many different mixtures. It is very flexible because several different compounds can be separated from each other in one experiment. ... However, TLC often works best with a very small amount of material.

Fourier Transform Infrared Spectroscopy, also known as FTIR Analysis or FTIR Spectroscopy, is an analytical technique used to identify organic, polymeric, and, in some cases, inorganic materials. The FTIR analysis method uses infrared light to scan test samples and observe chemical properties.

FTIR spectroscopy is used to quickly and definitively identify compounds such as compounded plastics, blends, fillers, paints, rubbers, coatings, resins, and adhesives. It can be applied across all phases of the product lifecycle including design, manufacture, and failure analysis.

Both techniques are not alike in many respects, and the differences are glaring. Thin layer chromatography (TLC) is meant to separate the solids and some liquids. ... Gas-liquid chromatography, on the other hand, is intended to separate gases. This technique uses gas as its mobile phase and liquid as the stationary phase.

You can identify an unknown substance by measuring its density and comparing your result to a list of known densities. Density = mass/volume. Assume that you have to identify an unknown metal. You can determine the mass of the metal on a scale.

Thin-layer chromatography (TLC) is a chromatography technique used to separate non-volatile mixtures. Thin-layer chromatography is performed on a sheet of glass, plastic, or aluminium foil, which is coated with a thin layer of adsorbent material, usually silica gel, aluminium oxide (alumina), or cellulose.
