Using FT-IR To Identify Unknown Contaminants

By Alan Xu and Chiara De Zorzi

Unknown particles, residues, and fibers in syringes, cartridges, vials, and combination products can compromise delivery-system performance, container integrity, and patient safety. In this white paper, Stevanato Group’s Technology Excellence Center (TEC) shares real-world case studies demonstrating how Fourier Transform Infrared Spectroscopy (FT-IR) supports contaminant identification, root-cause investigations, and corrective actions across pharmaceutical delivery systems. Learn how formulation, device, quality, and engineering teams can strengthen contamination-control strategies, improve delivery reliability, and reduce product-quality risk throughout the drug-delivery lifecycle.
