WitrynaAn automated workflow of synthetic peptide mass confirmation and impurities profiling was developed using the ACQUITY QDa Detector with MassLynx and ProMass. Impurities above 0.2% optical threshold were successfully detected and identified for eledoisin at 2 µg mass load. Witrynaimpurities • impurity profil of gabapentin without paying attention to the late eluting dimeric/oligomeric impurities (USP PF) • In the synthesis of a DS a primary amine is methylated to form a dimethylamino group. SST of peak to valley ratio between the main peak (dimethylamino compound) and the peak of the primary amine impurity.
