For biologic drug products this is especially critical – issues that can result are:
Drs. Liang Fang and Lloyd Waxman have described a systematic series of methods to understand surface chemistry and interactions in a recent report. The approach is two-fold. The first aspect comprises complementary use of six surface methods (infrared spectroscopy, plasma emission spectroscopy, x-ray photoelectron spectroscopy, scanning electron microscopy, atomic force microscopy, and secondary ion mass spectrometry) to precisely define composition of a component surface. The second aspect comprises methods to examine for generation of protein-based particles resultant from interaction with a component surface. From this series of methods, a very clear picture can be developed of the suitability of a component for a drug product. In particular, this report shows major differences between two elastomer components that are represented as having barrier properties resultant from lamination or applied surface coatings.
