HPLC Sorbenter
Ved at pumpe et tryksat flydende opløsningsmiddel med prøveblandingen gennem en HPLC-sorbentfyldt kolonne kan forskere identificere hver blandingskomponent ved hjælp af retentionstidsmålinger. Disse sorbenter kan arbejde med små partikelstørrelser, der kræver højt driftstryk – en almindelig egenskab ved højtydende væskekromatografi. HPLC-sorbenterne kan være hydrofobe eller polære og er i stand til at separere og kvantificere. De alsidige materialer fungerer med digitale mikroprocessorinstrumenter til hurtig testning.

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.

Ion exchange resins, Diaion® HP20
Supplier: Thermo Fisher Scientific
Diaion® HP20 is used as a filler in chromatography columns due to its extremely large pores. It is considered as an effective adsorbent to eliminate toxic effects in fermentation and separation of traces heavy metal ions. It is also useful for the purification of peptides, proteins, fermentation products, polyphenols and cephalosporin C. It helps to remove bitter tasting substances from fruit juices.
