Offset Raman Spectroscopy for Pharmaceutical Drying Monitoring

Spatially
Offset Raman Spectroscopy (SORS) is a technique to explore and collect
subsurface information non-invasively, addressing the main limitation of
conventional backscattering configurations. By collecting Raman signals at
varying source-detector distances, this configuration enables depth-resolved
measurements to provide more representative sampling.
This
webinar will highlight the advances of a novel SORS probe for in-line drying
monitoring using an industrial compound from pharmaceutical manufacturing. The
SORS monitoring setup employs a 785 nm laser with 45° incident angle as the
light source and collecting fibres corresponding to source-detector distances
of 0.0 mm (backscattering) and at 1.5, 2.5, and 3.5 mm distances. The
presentation will cover the application of the SORS probe to an agitated
filter-dryer and the potential challenges posed by the powder bed
characteristics on the monitoring of residual solvents.
This
webinar will take no longer than one hour.
This webinar is for CPACT members only.
