Overview
Named phases: Mono GPC
Separation categories: SEC
Available particle sizes: 5, 10 µm
Available pore sizes: 100, 100-1000, 300, 500, 1000 Å
Scientific principle
Size exclusion chromatography separates molecules primarily by their access to pores within the packing material. Larger species generally access less pore volume and elute earlier than smaller species.

What are SEPAX GPC Columns?
SEPAX GPC Columns are catalog-listed products for gel permeation chromatography. The family is intended for polymers and macromolecules, with available configurations shown in the specification table on this page.
How do GPC Columns work?
The separation is governed by molecular size and access to the pore network. Selectivity also depends on the exact phase, mobile phase, sample properties, temperature, flow rate and column dimensions.
How to select a configuration
Start with the required separation mechanism and named phase. Then compare particle size, pore size where listed, internal diameter, length and catalog number. Match the configuration to system pressure capability, sample load and the scale of the method.
Applications
This family is relevant to molecular-weight distribution and polymer characterization. Suitability must be confirmed experimentally with the actual sample and method conditions.
Method development
Begin with a documented method or a chemically reasonable starting condition for the selected phase. Control sample solvent strength, buffer compatibility, pH, ionic strength, gradient profile, temperature and injection volume. Change one variable at a time and record system-suitability results.
Column care and storage
Filter samples and mobile phases, prevent buffer precipitation, avoid sudden solvent incompatibility and stay within the product-specific operating limits supplied with the column. After use, remove strongly retained material with a compatible wash and store the column only in a suitable solvent for that exact phase.
Replacement and method transfer
Do not select a replacement by dimensions alone. Compare separation mechanism, stationary-phase type, particle size, pore size where applicable, column geometry and method conditions. Verify equivalence through retention, resolution, efficiency, tailing and system-suitability testing.

Troubleshooting guidance
Unstable baselines, pressure changes and distorted distributions may be caused by incomplete dissolution, particulates, solvent mismatch, air or temperature variation.
Cleaning and regeneration
Flush with clean compatible solvent and avoid rapid switching between solvents with very different polarity or viscosity. Store the column filled with an approved solvent.
Mobile phase recommendations
Use fully compatible organic solvents of consistent grade and viscosity. Dissolve and filter polymer samples completely, and match sample solvent closely to the mobile phase.
