Confident chiroptical insight for science and industry

Combining ZEBR’s precision engineering with Palacký University’s expertise, ROASPECT delivers the stereochemical confidence essential for critical decision-making.

ROASPECT is research-grade Raman Optical Activity spectrometer that measures molecular chirality directly in solution.

— In a single measurement, ROASPECT captures both the conventional Raman spectrum and its chiroptical ROA counterpart - chemical identity and molecular handedness, side by side. It links this vibrational fingerprint to absolute configuration and quantifies enantiomeric excess with sub-1 % precision in one minute - on samples down to 5 µL, with automated self-calibration. This is chirality you can trust - in research and in pharma.

Core

Applications

Absolute Configuration

Assign 3D stereochemistry directly from spectra – comparison of measured ROA with first-principles simulation resolves ambiguous configurations.

Enantiomeric Excess Quantitative

EE analysis in Raman-active chiral solutions – sub-1 % precision in one minute, <0.05 % standard deviation in EE after extended measurement.

Molecular Structure & Conformation

ROA is exquisitely sensitive to conformation, deuteration, molecular folding, weak intramolecular interactions and much more – structural details beyond conventional Raman.

Pharmaceutical Analytics

Chirality-sensitive measurement close to the point of decision – for development, analytical verification, and workflow exploration.

Chirality defines drug success. ROASPECT provides the stereochemical evidence essential for efficacy, safety, and commercial value.
