A new dimension in selectivity and sensitivity using differential mobility spectrometry


Challenged to remove matrix interferences while dealing with the evolving complexity of biotherapeutics? In this webinar we will detail how to overcome background interference challenges, which might otherwise limit assay capabilities, through exploring and examining multiple case studies. These include the elimination of endogenous interference in allopurinol assays and the resolution of matrix interference, as well as the simplification of sample preparation in rituximab quantitation.

You will learn how to:

  • How to eliminate endogenous/exogenous isobaric interference (e.g., isomers)
  • Methods for the reduction of chemical/background noise to improve S/N ratio and promote achievable LLOQs
  • What can be done to simplify exhaustive sample preparation and complex chromatographic separations
  • How to minimize time required for method development
  • Key advantages of SelexION+® technology

Who may this interest?

  • CROs, pharma and biotech organizations focused on enhancing selectivity for LC–MS quantitative bioanalysis
  • Mass spectrometrists and bioanalytical scientists engaged in assay development
  • Academics and students interested in the applications of ion mobility spectrometry
