Event Overview:
This webinar will discuss the adverse impact of particulate matter and aggregates for immunogenicity and the need to improve the characterization of submicron aggregates/particles in biopharmaceuticals. Optical Photothermal Infrared (O-PTIR) technology will be reviewed. The benefits of O-PTIR to perform nondestructive, simultaneous infrared (IR)/Raman measurements with submicron spatial resolution on particulate matter and aggregates in biopharmaceutical formulations (IV infusion in-use studies, stability and degradation studies) will be demonstrated.
Key Learning Objectives:
- Learn the impact of particles and aggregates in immunogenicity and toxicity.
- Understand how combining submicron IR and Raman microspectroscopy overcomes the limitations of traditional vibrational spectroscopy.
- Learn how O-PTIR microspectroscopy greatly improves knowledge and understanding of particles and aggregates in biopharmaceuticals.
Who Should Attend:
- Particle analysis/biopharmaceutical development scientists and engineers
- PAT and manufacturing engineers and scientists
- Regulatory compliance and quality operations scientific personnel

The bulky bench-top NIR spectrometer is quietly being dismantled and rebuilt as a wafer-scale photonic chip, a self-calibrating algorithm, and a sensor small enough to ride in a shirt pocket. What once demanded a grating, a moving mirror, and a climate-controlled lab now fits inside a handheld module, a bioreactor probe, or a drone payload, and it increasingly figures out what it is looking at on its own.
