Size Exclusion Columns

1.1 Introduction

ENrich prepacked columns for size exclusion chromatography are

designed for rapid and reproducible high-resolution separation of

biomolecules. Each column contains a unique, high-performance

size exclusion media based on spherical polymer beads modified

to provide quick, differential size–based diffusion.

1.2 The ENrich SEC Separation Media

ENrich SEC media is available with different exclusion limits

and separation ranges. The prepacked columns contain 10 μm

beads, which produce excellent resolution of biomolecules at low

backpressures. SEC 70 is ideal for separating biomolecules up

to 70,000 Da and SEC 650 is used for larger biomolecules up to

650,000 Da.

The 10 μm particle size and narrow particle size distribution

provide excellent resolution of biomolecules at high flow rates and

with relatively low backpressures. The hydrophilic ENrich media

demonstrates extremely low nonspecific binding of biomolecules

accompanied by high recovery of biological activity.

Stability

The columns are stable over the pH range 2–12, allowing easy
cleaning and regeneration.
