STRONG AND WEAK ANION AND CATION EXCHANGE CHROMATOGRAPHY COLUMNS
-All Columns are Compatible with Aqueous and Most Organic Solvents in the pH Range of 2-8
-300Å and 1000Å Pore Sizes for Superior Protein Separation and Recovery
-AX, S, Q, & CM Bonding chemistries are based on the original SynChropak® bonding technology.
AX300
Weak Anion Exchanger
AX300 support is a crosslinked polyethyleneimine phase on 7µ, 300Å, silica. Selectivity can be altered by mobile phase composition, and pH affects ionization of both the support and the solute. AX-300 permits analysis of proteins up to molecular weights of 200,000 daltons. AX300 has excellent recoveries and loading capacity.. e.g., 22mg ovalbumin can be loaded onto a 250x4.6 column with no overloading effects.
CM300
Weak Cation Exchanger
CM300 support has a polyamide coating containing carboxymethyl groups and is bonded to a 7µ, 300Å, silica. Selectivity can be altered by mobile phase salt composition, and pH affects ionization of both the support and the solute. CM-300 permits analysis of proteins up to molecular weights of 200,000 daltons and exhibits excellent recoveries as well as high loading capacity.
S300
Strong Cation Exchanger
S300 support has a polyamide coating containing sulfopropyl functional groups, bonded to a 7µ, 300Å, silica. Ionization of the functional groups on this bonded phase is constant above pH 3. S-300 columns are a good choice for the separation of basic proteins.
S1000
Strong Cation Exchanger
S1000 support has a polyamide coating containing sulfopropyl functional groups bonded to a 7µ , 1000Å, silica. Ionization of just the solute affected by pH above pH3. S-1000 columns are excellent columns for the fast analysis of glycosylated hemoglobin.support has a polyamide coating containing sulfopropyl functional groups bonded to a 7µ , 1000Å, silica. Ionization of just the solute affected by pH above pH3. S-1000 columns are excellent columns for the fast analysis of glycosylated hemoglobin.
Q300
Strong Anion Exchanger
Q300 support has fully quaternized, crosslinked polyethyleneimine phase on 7µ, 300Å silica. Ionization of this support has no pH dependence. Q-300 columns are excellent columns for the rapid separation of proteins and enzymes
