GPC is based on separation by molecular size rather than chemical properties. It employs the principle of size-exclusion chromatography (often referred to as SEC) to separate samples of polydisperse polymers into fractions of narrower-molecular-weight distribution. WebColumn chromatography separates substances based on differential adsorption of compounds to the adsorbent as the compounds move through the column at different rates which allows them to get separated in fractions. This technique can be used on a small scale as well as large scale to purify materials that can be used in future experiments. nrac registered disabled access consultants

WebJan 10, 2024 · The principle of gas chromatography. Components in the mixture are distributed between two phases, one of which is a stationary phase, and the other is a mobile phase gas, or carrier gas, that carries the mixture through the stationary phase.

WebJul 8, 2024 · The principle in gas chromatography involves the separation of volatile components of a sample between the mobile gaseous phase and stationary liquid phase. The solubility of a substance in between the gaseous mobile phase and stationary liquid phase is based on their partition co-efficient. The components of the sample that are … Gel permeation chromatography (GPC) is a type of size-exclusion chromatography (SEC), that separates analytes on the basis of size, typically in organic solvents. The technique is often used for the analysis of polymers. As a technique, SEC was first developed in 1955 by Lathe and Ruthven. The term gel permeation chromatography can be traced back to J.C. Moore of the Dow Chemical Company who investigated the technique in 1964. The proprietary column technology …

WebGel Permeation Chromatography, (GPC), also known as Size Exclusion Chromatography, (SEC) is really the easiest to understand of all the liquid chromatographic techniques.
