Conversely, crystalline material can act as nuclei for recrystallization and resulting in instability of amorphous systems. Raman spectroscopy is .. Read more sensitive to polymorphic differences and amorphous content in pharmaceutical materials. This make Raman spectroscopy a powerful process analytical technology (PAT), when combined with multivariate modelling, to control the amorphous content in a pharmaceutical process. The results clearly demonstrate that Raman spectroscopic techniques combined with multivariate methods is a powerful and effective tool for quantitation of amorphous content in crystalline material with applications ranging from API isolation, milling and to multiple unit operations in DP manufacturing. Her lead role in the organization is to support investigations in drug substance and drug product development related to process-induced amorphization, form conversion using spectroscopic tools such as IR, Raman and confocal Raman spectroscopy. Darren has worked with applied analytical techniques for more than 20 years in positions from laboratory technician through to product manager. Over these 20 years, Darren has developed a keen interest in taking complex analytical techniques and developing systems and workflows to make them simple.
