The basic techniques in adsorption TLC consist of a single development, if this proved in … WebOne of those methods is known as thin-layer chromatography, or TLC for short. This works like all other kinds of chromatography in that you have a mobile phase and a stationary phase, and the compounds that you're trying to separate interact with these two phases. First, let's talk about the stationary phase.
WebIt is the development solvent that effects the separation. What’s going on at the molecular level during development? There are three components in TLC: (1) the TLC plate (stationary phase), the development solvent (mobile phase), and the sample to be analyzed (solute). In our experiment the TLC plate consists of a thin plastic sheet covered ...
