Targeted LC-MS/MS detection of lipid impurities in lipid nanoparticles

Lipid nanoparticles (LNPs) became famous for the rapid development and largescale production of vaccines during the COVID-19 pandemic. Theses vaccines consist of mRNA coding for an antigen encapsulated in LNPs. Because the mRNA is sensitive to inactivation by distinctive oxidation products of the lipids, special care in quality control of the formulations and raw materials is required. Here, we suggest a workflow for HPLC-MS/MS detection of lipid related impurities in LNP formulations, independent of impurity standards.
