GLP and GMP XRD services are available and can be applied to stability studies or QC release testing. Pharmaceutical intermediates, APIs and final products can frequently exhibit polymorphism. XRD is routinely used to observe polymorphic changes that may occur during storage or manufacturing. Temperature and time variations on storage can initiate changes in the original powder pattern. Often formulation of the final stage of the drug delivery system can cause changes to the crystallinity from grinding, packaging or mixing effects.
