Direct analysis of class 2 residual solvents using Molecular Rotational Resonance spectroscopy
7 Aug 2025
Testing for residual solvents in pharmaceutical products has traditionally been performed using chromatography techniques, however, these cannot detect several residual Class 2 solvents.
Discover an alternative analytical technique that uses Molecular Rotational Resonance (MRR) spectroscopy, which offers chemical selectivity and bridges the gap for the analysis of low-volatile residual solvents from USP Residual Solvents Class 2.
