Promix Technology

Applications:

  • Proteomics
  • Peptide/Protein Analysis
  • Peptide/Protein Purification

Features & Benefits:

  • 2-D HPLC with a Single Column
  • Ionic Interactions
  • Reversed-Phase
  • Separate peptides and proteins that differ only by a single amino acid
  • Enhanced selectivity for closely related peptides and proteins.
  • Increased peak capacity compared to reversed-phase and ion exchange.
  • Increased LC-MS sensitivity using formic acid and ammonium acetate.
  • Completely Scalable from capillary to prep
Promix™ Technology

Independent control of acid/buffer concentration and organic modifier

offers almost limitless control of retention and selectivity!
