Promix SP is a stationary phase designed for small peptides under 1 kDa with a pI value below 6.0. This mixed-mode analytical column features negatively-charged acidic ion-pairing groups embedded within long ligand chains.
– Utilizes reverse-phase and ion-exchange mechanisms of interaction.
– Requires an acidic mobile phase with a pH range of 2 to 5.5.
– Recommends an ionic modifier concentration of at least 20 mM.
– Available in a 100Å pore size.
