The Rf value (retardation factor/Retention Factor) is an important parameter inchromatographythat represents the distance traveled by a particular compound relative to the distance traveled by the solvent front. The Rf value is a dimensionless number that ranges from 0 to 1. It is calculated by ...
What are interactions that result in a small RF value in chromatography? The properties of a compound are often very different from the properties of the elements making up the compound. Water is an excellent example of this idea. Discuss. ...
Nowadays, separation of low molecular weight sugars is usually performed by HPLC in two prevailing modes: (i) anion or cation ion-exchange chromatography (on metal-loaded cation exchangers based on a resin or a silica substrate), or (ii) HILIC on amino-propyl modified ...
