Residual Solvent Analysis Landing Page

Molecular rotational resonance (MRR) spectroscopy enables structure-specific residual solvent analysis across pharmaceutical, chemical, and research workflows. By generating highly specific molecular fingerprints, BrightSpec's MRR instruments help scientists identify and quantify residual solvents even in complex sample matrices.

Unlike traditional approaches that often rely on chromatographic separations and extensive method development, MRR provides direct molecular information that simplifies residual solvent analysis while supporting confident analytical decisions.

Solving Common Residual Solvent Analysis Challenges with MRR Spectroscopy

Your Challenges

Analytical chemists performing residual solvent analysis must accurately identify and quantify trace volatile impurities across diverse chemistries, manage time-intensive GC method development, and ensure reliable results in complex sample matrices without slowing down workflows.

Our Solution

MRR simplifies residual solvent analysis into a single, automated measurement. Chemists can directly identify and quantify trace solvents with high selectivity and linearity, eliminating extensive method development, reducing hands-on time, and delivering reliable results without chromatographic separation or complex sample preparation.

Key Applications

MRR supports residual solvent identification, quantitation, and monitoring across a wide range of analytical workflows.

Frequently Asked Questions

How does MRR simplify residual solvent analysis?

MRR simplifies residual solvent analysis by removing the need for chromatographic separation and replacing it with direct, fingerprint-based molecular detection and quantitation.
What are the advantages of MRR compared to traditional techniques like GC-MS and NMR?

A single MRR measurement can provide solvent identification and quantitation while reducing method development and chromatographic complexity.
What types of molecules are suitable for MRR analysis?

MRR works best with small molecules. To read a molecule's molecular "fingerprint", MRR requires molecules to have a dipole moment and to have polarity.
