Screening of nitrosamines by LC-HR-MS/MS technique – we detect trace amounts in active substances (APIs), products and raw materials.
Our specialized service based on LC-MS/MS technique enables precise identification of the chemical structure of impurities present in samples of raw materials, active substances and finished drug products.
Monoclonal antibody analysis by LC-HR-MS/MS – MAM – glycosylations, peptide maps, disulfide bridges, PTMs, TiPOS studies, etc.
We achieve high sensitivity, selectivity and precision by individually selecting method parameters depending on the drug and expected nitrosamines.
