SCX Column

Silica-based packing with octylsulfonate groups covalently bonded to the surface, which can be ionized at a pH greater than 3.

S-300 type is a good choice for separating basic proteins.

S-1000 type can be used excellently for rapid separation of glycated hemoglobin.

SAX Column

Silica-based packing with high-density quaternary ammonium ion groups covalently bonded to the surface, which are not influenced by pH for ionization.

Q-300 type is excellent for the rapid separation of proteins and enzymes.

WAX Type

Silica-based packing with polyethyleneamine covalently bonded to the surface, where the pH value can simultaneously affect the degree of ionization of both the column stationary phase and the mobile phase.

AX-300 type is used for separating proteins up to 200,000D in molecular weight, with high recovery rate and loading capacity.
