Simulation-Aided Process Development

  • November 24, 2025
  • by Ypso-Facto
Reverse-phase chromatography (RPC) is a key technique for peptide purification, but establishing robust processes remains experimentally intensive and time-consuming. Mechanistic modeling provides an efficient route to accelerate process development by reducing the number of experiments while enabling a deeper understanding of chromatographic behavior. In this work, a mechanistic model was developed for the reverse-phase purification of peptides. The model combines the mixing-cell approach with a linear driving force (LDF) approximation and a dedicated... Read more
