Al-A
Neutral alumina is a highly polar SPE adsorbent with a neutral surface treatment. It can interact with the aluminum metal center to form hydrogen bonds or charge exchange adsorption molecules on the surface of the surface silanol group. For heterocyclic substances containing nitrogen, phosphorus and sulfur groups, negative compounds such as Aromatic hydrocarbon and organic amines have strong retention ability. It is widely used for sample pretreatment of Sudan red and Malachite green.
Al-A
GREEN MALL Alumina-A is an alumina adsorbent with an acidic surface (pH=4.5) It can be used as a strong polar adsorbent and a medium cation exchanger.
Al-B
The alkaline alumina SPE adsorbent obtained by treating acidic alumina with an alkaline solution has a negative surface charge and a similar cationic bonding effect.
