SPE Column--Alumina

Description：

GREEN MALL Alumina-N

Neutral alumina strong polar SPE adsorbent, whose surface treatment is neutral, can interact with aluminum metal center to form hydrogen bond or point charge with surface silanol groups for ion exchange adsorption molecules. It has strong retention ability for heterocyclic substances containing nitrogen, phosphorus and sulfur groups, aromatic hydrocarbons, organic amines and other rich point compounds. It is widely used in sample pretreatment of Sudan red and malachite green. The particle size of green mall alumina-n is 50-200μm。

GREEN MALL Alumina-B

The alkaline alumina SPE adsorbent obtained by treating acidic alumina with alkaline solution has a negative charge on the surface and is similar to cationic bonding.

GREEN MALL Alumina-A

Green mall alumina-a is an alumina adsorbent with acidic surface (pH = 4.5), with particle size of 50-200μm.It can be used as strong polar adsorbent and medium cation exchanger.
