SEC Columns
Size-based separations of peptides, proteins, and viral vectors
Get unmatched batch-to-batch reproducibility with the wide range of Waters Size-Exclusion Chromatography (SEC) Columns and standards for protein and peptide characterization.
SEC is a powerful technique for aggregate and fragment analysis in the research, development, and manufacturing of biotherapeutic proteins, such as insulin and monoclonal antibodies (mAb). With SEC, also known as gel filtration, you can separate proteins based on their size (hydrodynamic radii versus absolute molecular weight) in solution, with larger sized species eluting before smaller proteins.
The pore size and volume of the SEC particles used in the packed column drives this isocratic based technique, so the column you choose matters. As the molecular weight of the proteins of interest increases, SEC columns with comparatively larger pore size particles are selected.

Choose the right SEC Column for your lab
SEC is ideal for aggregate and fragment analysis in the research, development, and manufacturing of biotherapeutic peptides, proteins, and viral vectors, but choosing the right column for your analysis is important. Use the following criteria to choose a column that provides reliable, high quality SEC analyses of various biomolecules, including insulin, monoclonal antibodies, and adeno associated viruses (AAVs).
What to consider when choosing an SEC Column:
What is the molecular weight of your sample?
What is the dispersion of your LC system?
Are you separating components <2 fold difference in molecular weight (MW)?
Are you separating components >2 fold difference in MW?
