A Brief Introduction Of SPE And SPE Cartridge

The capacity of the SPE cartridge refers to the adsorption amount of the SPE cartridge packing. For silica-based SPE cartridge, the capacity is generally 1 to 5 mg/100 mg, that is, the cartridge capacity is 1%~5% of the mass of the packing. The capacity of the bonded silica ion exchange adsorbent packing is expressed in meq/g, that is, the capacity per gram of the filler is X milliequivalent. The capacity of such packing is usually between 0.5 to 1.5 meq/g.

There are many SPE cartridge packing types: C18, C8, NH2, CN, silica gel, alumina, Florisil, diatomaceous earth, polyamide, activated carbon, Diol (diol based), graphitized carbon black, XAD-2, GDX- 403, HLB, graphitized carbon black/amino filler, macroporous adsorption resin, and the like.
