Besides high quality solvents for HPLC Avantor Performance Materials also offers chromatographie products for HPLC separations. BAKERBOND sorbents of J.T. Baker are highly efficient and effective media which are synthetized with trifunctional silane chemistry. Sorbents of J.T. Baker are made out of bounded phases of small and large pored, spheric and unregular formed silica particles as well as spheric polymere media. Silica based BAKERBOND media are available as packed columns for every HPLC separation.
Ion exchange chromatography is applied especially for separations of biomolecules, e. g. proteins and peptides. With this method samples are separated by ionic interactions between the different charge of molecules in sorbence and mobile phase. At ion exchange chromatography cation and anion exchange chromatography are distinguished. In general elution is caused by changing pH value or ion concentration of the mobile phase.
Avantor Performance Materials produces a number of sorbents out of silica with spheric and unregular formed particles to separate small molecules as well as large ones. BAKERBOND silicas of J.T. Baker with spheric particles are characterized by a higher mechanicle solidity as silica with unregular formed particles.
