Optimizing LC Separations for Therapeutic Peptide Impurities

Tuesday, June 16, 2026
8am PDT | 11am EDT | 4pm BST | 5pm CEST

Therapeutic peptide impurity characterization presents ongoing challenges due to closely related variants, stereoisomers, and process‑induced modifications. This virtual event highlights practical LC separation strategies that enhance resolution, robustness, and sensitivity through mobile phase additive and temperature optimization. Attendees will gain insight into how bio‑compatible, inert LC column technologies improve impurity discrimination and method performance under high‑load, process‑relevant conditions.

 

Topics include:

  • The benefits of inert LC columns for peptide analysis
  • LC strategies for resolving complex peptide impurities
  • How additives and temperature affect peptide separations
