Hybrid LBA/LC–MS developments & benefits

0

During this panel discussion we discussed how hybrid LBA/LC–MS assays are used, reflecting on the use of the technique in analysis of large molecules. We also discussed methodological practices, covering internal standards, purification methods and detection platforms.

Our panelists addressed the benefits of using hybrid LBA/LC–MS compared with LBA and LC–MS individually. With a wealth of experience, our experts provided relevant insight on key issues surrounding hybrid LBA/LC–MS technology and offered advice on best practice.

What will you learn?

  • Development of hybrid LBA/LC–MS assays
  • Internal standards and methodological practices to apply
  • Acceptance criteria to apply for drug analysis
  • Advantages of utilizing hybrid techniques versus LBA and LC–MS individually

Who may this interest?

  • CROs, pharmaceutical and biotechnology companies focused on LC–MS/MS quantitative bioanalysis of large molecules
  • Small molecule (LC–MS) bioanalytical scientists with an interest in large molecule quantitation
  • Bioanalysts with a background in LBAs interested in LC–MS
