What are SEPAX Protein Standards?
SEPAX Protein Standards are catalog-listed products for protein system suitability and calibration. The family is intended for protein-focused chromatographic methods, with available configurations shown in the specification table on this page.
How do Protein Standards work?
The separation is governed by comparison with a defined reference material under the selected method conditions. 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 system suitability, calibration and performance monitoring. 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
Unexpected standard profiles may indicate degradation, aggregation, adsorption, excessive injection volume or a system/column performance issue.
Cleaning and regeneration
Store standards according to their individual handling requirements and prepare fresh working solutions when stability is limited. Keep solutions free from particulates and aggregates.
Mobile phase recommendations
Prepare standards in a buffer compatible with the SEC method and avoid repeated freeze–thaw cycles. Use concentrations that produce reliable detector response without overloading.
Related SEPAX product families
For complementary selectivity or workflow steps, also review SEC Columns, Proteomix Columns and Antibodix Columns. These related families can support orthogonal method development, sample cleanup, confirmation or scale-up depending on the application.
