WebPhosphate, Ion chromatography standard solution, Specpure®, PO4⁻3 1000µg/ml Reversed-phase chromatography (RPC) is any liquid chromatography procedure in which the mobile phase is significantly more polar than the stationary phase. It is so named because in normal-phase liquid chromatography, the mobile phase is significantly less polar than the stationary phase. Hydrophobic molecules in the mobile phase tend to adsorb to the relatively hydrophobic stationary phase. Hydrophilic molecules in the mobile phase will tend to elute first. …

WebHydrophobic-Interaction Chromatography [HIC] HIC is a type of reversed-phase chromatography that is used to separate large biomolecules, such as proteins. It is usually desirable to maintain these molecules intact in an aqueous solution, avoiding contact with organic solvents or surfaces that might denature them. WebGel Permeation Chromatography, (GPC), also known as Size Exclusion Chromatography, (SEC) is really the easiest to understand of all the liquid chromatographic techniques. The separation is based strictly on the size of the sample in solution, and there should be no interaction with the column packing, (adsorption, partition, etc.), as you have ... WebFeb 6, 2024 · 1. Put water in a cup. When doing simple chromatography, your solvent (the liquid that carries the mobile phase across the … empower vs personal capital
