Streamline Excipient Testing with Molecular Rotational Resonance Spectroscopy

Excipient testing requires reliable identification and quantitation of trace impurities that can impact product safety, quality, and regulatory compliance. Common excipients such as PEGs often pose analytical challenges because of complex matrices, high viscosity, or demanding sample preparation.

Molecular rotational resonance (MRR) spectroscopy enables structure-specific analysis of excipients and excipient-related impurities. By generating highly specific molecular fingerprints, MRR helps scientists identify and quantify target analytes with minimal sample preparation, reducing analytical complexity while delivering confident results for pharmaceutical development and quality control applications.

 

Solve Excipient Testing Challenges with MRR

Challenge

Analytical scientists must accurately identify and quantify trace impurities in excipients while meeting regulatory expectations. Traditional methods often require extensive sample preparation, chromatographic separations, and time-consuming method development that can slow analytical workflows.

Solution

MRR enables direct, structure-specific analysis of excipients and impurities with minimal sample preparation. Scientists can identify and quantify target compounds faster, reducing method development and analytical complexity while maintaining confidence in their results.
