Simplify Chiral Analysis with Molecular Rotational Resonance (MRR) Spectroscopy

BOOK A DEMO

Differentiate Enantiomers Without Chromatography

Molecular rotational resonance (MRR) spectroscopy enables direct chiral analysis through highly specific molecular rotational fingerprints. From enantiomeric purity assessment to stereochemical confirmation, BrightSpec's MRR instruments help scientists differentiate closely related stereoisomers with exceptional confidence.

By providing direct molecular information, MRR reduces analytical complexity and supports chiral analysis without chromatography, derivatization, or extensive method development.

Solving Common Chiral Analysis Challenges With MRR Spectroscopy

Your Challenges

 Analytical chemists performing chiral analysis must distinguish enantiomers with high confidence, rely on specialized techniques like chiral chromatography or derivatization, and manage complex workflows that increase time, cost, and method variability. 

Our Solution

MRR enables direct chiral analysis without chromatography or derivatization. By measuring molecule-specific rotational fingerprints, chemists can identify and differentiate enantiomers with high confidence in a single measurement, while simplifying workflows and reducing analysis time.
