High Capacity Quaternary Amine, HQ

High Capacity Strong Anion Exchangers  (Quaternary Amino Methyl)

• Product Summary:

The proprietary polymerization technique ensures that the packing is not brittle and free of any leachable.
STYROS® HQ 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®  HQ
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 Quaternary Amino Methyl
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 Quaternary Amino Methyl are provided in PEEK and Stainless Steel columns of different sizes.
