Vaisman's presentations will be part of the Particle Characterization session which will take place on the afternoon of Tuesday 27 January 2015.

IFPAC 2015 will take place in Arlington in the US state of Virginia. Vaisman’s presentations will cover the ‘Applications of Dynamic Light Scattering as PAT for on-line nano-particle characterization’ and ‘In-situ monitoring of high shear and fluid bed processing using spatial filter velocimetry’, which are currently two very popular topics within the pharmaceutical production industry.

Dynamic light scattering (DLS) is an important technique used in the particle sizing of proteins, colloids and dispersions. The observation of scattered light allows defining characteristics of a particle dispersion or molecular solution such as particle size, molecular weight and zeta potential to be determined.

The growing importance of large molecule based therapeutics and the drive to decrease the particulate size of small molecule APIs, is creating new challenges for in-process particle characterization.

Advances in process development and manufacturing control are being supported by the automation of dynamic light scattering (DLS) measurements coupled with the use of this equipment as a process analytical instrument.

Vaisman’s first topic will cover various examples of how on-line DLS can be applied to processes such as emulsification and nano-milling.

His second topic will consider the other end of the particle size spectrum and will analyse the application of PAT instruments based on spatial filter velocimetry for in-situ particle size testing within fluidized bed and high shear granulation methods during pharmaceutical production.

Vaisman will also touch upon the application areas of the method to monitor coating layer thickness and how agglomeration during Wurster coating can be determined.
