High Capacity Polyamine, HPA

High Capacity Weak Anion Exchanger, HPA

• Product Summary:

The proprietary polymerization technique ensures that the packing is not brittle and free of any leachable.
STYROS® HPA provides high 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:
High protein capacity (measured with BSA)
90 mg/ml for STYROS®  HPA
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.


Support Matrix  Cross-linked Poly(styrene-divinylbenzene)
Surface Functionalities Polyamine
Shipping Solvent  30 % MeOH in DI Water
Packing Density 0.4 g/ml
Shrinkage/Swelling < 0.5 % under different salt or solvent concentrations
Maximum Pressure Tolerance 207 bar (3,000 psi, 21 MPa)

High Capacity Polyamine are provided in PEEK and Stainless Steel columns of different sizes.
