WitrynaSynthetic peptide impurity profiling via LC-UV-based techniques requires optimization of peak resolution and detector response. For this study, a 20 minute gradient was found to resolve 11 impurity peaks from the main peak as shown in Figure 1. ICH guidelines recommend impurity identification to be based on total daily intake.
