STYROS™ DEAE is a
monolithic, fully uniform polymer based packing for anion exchange
chromatography of biomolecules such as proteins and peptides, as well as smaller
molecules, intended for use in high speed, high resolution applications.
The base matrix that is fully pervious is made of highly crosslinked
poly(styrene-divinylbenzene).
Our proprietary polymerization technique ensures that the beads are not brittle
and as a result, free of any leachables.
The unique macroporous structure takes full advantage of the inner bead's
surface area making it possible to run high speed, high resolution separation
without any mass transfer restrictions.
STYROS™ DEAE provides high
static and dynamic capacity for analytical and semi preparative separations.
It has an extremely high pressure tolerance, and can be used up to 5,000 psi.
High resolution separation can be achieved at high, as well as low flow rates.
The goal has been to provide seamless series of stationary phases that could
facilitate the transition from analytical to semi preparative and preparative
applications, all within the same products.
Our proprietary column packing are geared towards providing high batch to batch
reproducibility.
Feature 1:
Optimum protein capacity (measured with BSA)
85 mg/ml for STYROS™ DEAE
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:
4,000 psi for the XH series,
3,000 psi for the XP and XM series.
4,000 psi for the NB series
4,000 psi for the MB series
Feature 3:
No measurable shrinking and/or swelling
due to highly
crosslinked nature of the beads.
