Quantitation Molecular Rotational Resonance Spectroscopy

Molecular rotational resonance (MRR) spectroscopy enables structure-specific quantitation across a wide range of analytical applications. From impurities and degradation products to residual solvents and complex mixtures, BrightSpec helps scientists generate confident quantitative results by leveraging highly specific molecular spectral fingerprints.

By providing direct molecular information and exceptional molecular selectivity, MRR supports quantitative analysis across challenging analytical applications.

Solving Common Quantitation Challenges With MRR Spectroscopy

Your Challenges

Accurate quantitation can be difficult when compounds are present in complex matrices, exist alongside closely related impurities, or require highly selective analytical measurements. Traditional workflows may rely on derivatization, extensive sample preparation, or complex chromatographic methods, increasing analytical complexity and reducing confidence in quantitative results.

Our Solution

BrightSpec's MRR spectroscopy enables structure-specific quantitation through highly specific molecular spectral fingerprints. By directly measuring molecular rotational spectra, scientists can confidently quantify target compounds, impurities, and degradation products without chromatography or derivatization, while reducing sample preparation and simplifying workflows.

Frequently Asked Questions

What is quantitative analysis?

Quantitative analysis determines the concentration or amount of a compound within a sample.
How does MRR spectroscopy support quantitation?

MRR generates highly specific molecular spectral fingerprints that support confident quantitation of target compounds, impurities, and degradation products.
Can MRR quantify closely related compounds?

Yes. MRR's structure-specific measurements help distinguish and quantify compounds that may be difficult to resolve using conventional analytical techniques.
What industries benefit from MRR quantitation?

Pharmaceutical, chemical, consumer products, food & beverage, and flavor & fragrance are some examples of industries that can benefit from MRR-enabled quantitation.
Which BrightSpec instruments support quantitation workflows?

Both the spectraMRR and isoMRR platforms support quantitative analysis workflows. isoMRR is optimized for library-based quantitation, while spectraMRR combines quantitation with structure identification and library building capabilities.
