-300Ã… and 1000Ã… 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 6-7µ, 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 6-7µ, 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 6-7µ, 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 6-7µ, 300Å silica. Ionization of this support has no pH dependence. Q-300 columns are excellent columns for the rapid separation of proteins and enzymes
