A comparison of vibrational techniques for material verification
by Ahura Scientific, Inc.
Fourier-transform infrared (FTIR), near-infrared (NIR), and Raman are three related analytical techniques for vibrational spectroscopy. Vibrational spectroscopy is known to be highly selective at the molecular level, producing a spectral fingerprint of each compound, thereby being well-suited for raw material and final product identification and verification. This technical note provides a brief overview of each technology, followed by a tabulated discussion of questions concerning validation and performance. The author points out that Raman’s ease of sampling, due to its independence from packaging materials as well as water and humidity, will benefit users who have struggled with applying FTIR and NIR techniques to these applications.
