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 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
