Abstract
Methods of screening a glass container for storing a pharmaceutical formulation for susceptibility to lamellar silica formation includes filling the container with a buffer for the pharmaceutical formulation, storing the container with the buffer and optically analyzing the buffer after storage for one or more particles in the buffer. The one or more particles can be analyzed to determine a morphology and chemical composition and the interior surface of the container, once emptied, can be analyzed for delamination type deformation. The presence of particles in the buffer having a chemical comprising silicon, oxygen, and carbon and the absence of delamination type deformation is indicative of susceptibility to lamellar silica formation.
