Lipid nanoparticles (LNPs) are effective non-viral carriers, which are widely used as delivery vehicles for gene-based drugs such as messenger RNA (mRNA). To mitigate safety risks and ensure product efficacy, it is important to comprehensively characterize the lipids used for LNPs and their related impurities, as well as the mRNA integrity, purity and its critical quality attributes (CQAs).
Malte Hübschen of the University of Duisburg-Essen (Germany) discusses an automated gas chromatography-tandem mass spectrometry (GC-MS/MS) workflow that improves phthalate detection in tricky oils with LCGC International.
Liquid chromatography–ion mobility spectrometry–high-resolution mass spectrometry (LC–IMS–HRMS) shows elephant seal pups carry more PFAS than their mothers do.
