Theory of thin layer chromatography

Webb22 okt. 2024 · Thin layer chromatography (TLC) is a technique widely used in industrial and research chemistry. It is an inexpensive and simple technique, which makes it attractive for undergraduate chemistry lab experiments. Unfortunately, the technique is sometimes incorrectly taught.

Stationary Phases for Modern Thin-Layer Chromatography

Webb1 jan. 2013 · Theory TLC is a type of liquid chromatography in which the mobile phase is liquid and the stationary phase is a thin layer of material on top of a flat plat. This layer of material is known as the sorbent. The mobile phase is known as the developing solvent, and it transports the solutes through the stationary phase. Webbchromatography, technique for separating the components, or solutes, of a mixture on the basis of the relative amounts of each solute distributed between a moving fluid stream, called the mobile phase, and a contiguous stationary phase. The mobile phase may be either a liquid or a gas, while the stationary phase is either a solid or a liquid. Kinetic … the markets bellingham wa https://mertonhouse.net
