Polymeric chromatography and adsorbent media capture, purify and polish target molecules in bioprocessing and fine-chemical manufacture. Selectivity comes from the base matrix, the functional group, and the particle and pore size distribution.
Screen at the intended residence time
Bed geometry, linear velocity and residence time govern resolution and dynamic binding capacity. Screen on a small column at the residence time you intend to run, rather than extrapolating from static capacity — the two rank media differently.
Particle size trades resolution against pressure drop
Smaller particles sharpen peaks and raise back pressure. The right choice depends on the column hardware and the acceptable cycle time, not on resolution alone.
Handling and storage
Media supplied hydrated must not be allowed to dry. Follow the manufacturer's storage, sanitisation and storage-solution guidance for the specific grade; the requirements differ between grades and are on the product data sheet.
