Abstract

Vibrational and X-ray spectroscopic techniques are based on the interaction between radiation and matter. This interaction produces various signals that can be detected and that contain information about the morphology, structure or composition of molecules analyzed. When combined together, these complementary techniques are very powerful and facilitate the identification of the samples investigated. Nevertheless, prior sample preparation plays an important role in this identification, since it should allow combining analytical methods without damaging the samples. Through 5 case studies involving visible particles found in various containers, this article shows how an accurate sample preparation procedure associated to a combination of Infrared, Raman and energy dispersive X-ray (EDX) spectroscopies applies for the troubleshooting of foreign matters in pharmaceutical drug products. The forensic investigation procedure proved to be successful for the precise identification of samples.
