Chromatography Sorbents
Sorbents assist with separating mixture compounds in any of the chromatography methods. Ready-to-use chromatography sorbents make any isolation, identification, or purification procedure fast and simple. Stationary phase sorbents are offered in different particle sizes or polarities to match the chemical and physical properties of sample compounds for precise results. Chromatography sorbents may come with or without additives such as binders for stabilization or fluorescent indicators to compensate for hard to see ultra-violet ranges.

Ion exchangers
Supplier: Merck
In general, ion exchangers consist of a cross-linked polymer matrix with a uniform distribution of fixed ionic groups sited throughout the resin structure. These must be balanced by a similar number of ions of the opposite charge, (counter ions) to maintain electrical neutrality. Cation exchangers therefore, exchange and enrich only cations, anion exchangers only anions. In contrast adsorber resins have a non ionic, but depending on the structure, a somewhat polar character, and don't adsorb stoichiometrically both: anions, cations, as well as uncharged compounds.
