🧠 What Is Size Exclusion Chromatography (SEC) for Peptide Characterization?
Size Exclusion Chromatography (SEC) for Peptide characterization separates molecules based on their hydrodynamic radius. Unlike charge or chemical affinity-based methods, SEC focuses purely on size—making it ideal for studying purity, aggregation, and oligomerization in GLP-1 analogs.
At ResolveMass Laboratories, every SEC analysis is performed using high-performance columns and dual-detector systems under strict GLP standards. These dual detectors provide complete molecular profiling, detecting even minor aggregates. The technique also allows comparison of peptide batches over time to identify early degradation or instability.
Key Benefits of SEC for Peptide Characterization
- Non-destructive molecular separation
- High reproducibility for complex peptide systems
- Accurate detection of aggregates and oligomers
- Consistent batch-to-batch quality verification
- Full compliance with global regulatory guidelines

FAQs on Size Exclusion Chromatography (SEC) for Peptide
Size Exclusion Chromatography (SEC) for Peptide analysis is ideal because it separates molecules based solely on their size without altering their natural structure. This allows scientists to accurately determine molecular weight, purity, and aggregation levels, providing a complete understanding of peptide stability and integrity.
Unlike reversed-phase chromatography, which separates molecules by hydrophobicity, SEC for Peptide characterization works on the principle of molecular size. This makes SEC the preferred technique for studying peptide aggregation, purity, and conformational stability without changing the sample composition.
At ResolveMass Laboratories, SEC analysis is performed using advanced detectors like MALS, RI, and UV. These instruments provide both absolute and relative molecular weight measurements, helping researchers obtain precise data on peptide structure, purity, and aggregation behavior in a single run.
Yes. Size Exclusion Chromatography (SEC) for Peptide is highly effective at detecting and quantifying aggregated species. By separating monomers from dimers or higher-order aggregates, SEC helps evaluate peptide stability and ensures that therapeutic candidates maintain their required structural uniformity.
ResolveMass Laboratories uses gentle buffer systems such as phosphate-buffered saline (PBS) or phosphate buffers with mild surfactants. These buffers maintain peptide solubility, reduce non-specific binding, and preserve the sample’s natural conformation throughout the SEC analysis process.
Absolutely. SEC for Peptide analysis can be tailored with optimized columns and detectors to resolve even small peptides below 2 kDa. The method’s sensitivity and precision make it an excellent choice for detailed analysis of short peptide chains or synthetic analogs.
Yes. ResolveMass Laboratories designs customized SEC workflows to match each peptide’s molecular weight, size, and stability requirements. This personalized approach ensures consistent, reproducible results tailored specifically for each client’s GLP-1 analog or peptide therapeutic project.
