Chromalite PCG950 is a hydrophilic, highly crosslinked, porous polymethacrylic adsorbent. The pore size and matrix are designed for adsorption and reverse phase chromatography purification of biomolecules including small proteins, peptides, antibiotics and small molecules.

Chromalite PCG950 is more hydrophilic than PCG600, PCG900 and PCG1200 due to its aliphatic structure.
It is an excellent technical and economical choice for high-resolution low-pressure chromatography, suited for operation within the entire range of pH and for cleaning in place with most organic solvents and dilute acids and base.

Equivalent to AmberChrom™ CG71
