Addressing Analytical Risk from Non-Specific Adsorption in Biotherapeutic Methods

During chromatographic analysis of complex biotherapeutics, analytes may contain electron-rich functional groups that have an affinity to metal surfaces and may cause issues such as poor peak shape. Join this webinar to learn how Waters addresses these challenges.

Event Overview:

During chromatographic analysis of biotherapeutics, analytes with phosphate, carboxylate, or other electron-rich functional groups may adsorb non-specifically to metal surfaces. Non-specific adsorption leads to poor peak shape, lost recovery, and irreproducibility. This reduces method robustness, increases method development time, and adds risk to your separations. Currently, long, inconsistent, and transient passivation protocols are employed to address these challenges.

Newer column technologies address these challenges and enable stable platform methods that provide:

• Robust platform SEC methods
• Improved deamidation monitoring during peptide mapping
• Increased sensitivity for intact and subunit protein analysis
• Enhanced analysis of sialylated and phosphorylated glycans

Key Learning Objectives

• How and why certain analytes are lost to metal surfaces
• Limitations of existing solutions to address loss of analytes
• How new column technology solves the challenge of non-specific adsorption for metal sensitive analytes in bioseparations
• The chromatographic and analytical advantages across multiple bioseparation applications

Who Should Attend

• Biopharma Market
• Analytical Development Scientist
• Formulation Development Scientist
• Bioprocess Development Scientist
• Discovery/early Research Scientist
• QC Scientist or Technician
