Low Capacity Polyamine, PA
Low Capacity Weak Anion Exchangers, PA (Polyamine)
• Product Summary:
The proprietary polymerization technique ensures that the packing is not brittle and free of any leachable.
STYROS® PA provides Medium static and dynamic capacities to enable high throughput separation and purification during analytical and preparative runs.
STYROS® media are available in many different size columns both in PEEK and Stainless Steel.
• Key Features:
o Feature 1:
Medium protein capacity (measured with BSA)
30 mg/ml for STYROS® PA
o Feature 2:
Although we have used pressures of up to 10,000 psi without irreversibly altering the structure of the beads, we recommend the following pressure limits:
3,000 psi for the XH series
3,000 psi for NB series
3,000 psi for the MB series
2,000 psi for Micro Trap columns
2,000 psi for Silica Capillary columns
o Feature 3:
No measurable shrinking and/or swelling due to highly cross-linked nature of the beads.
