High-Stability Raman Systems
The mechanical components of a Raman spectroscopy system can move slightly with changes in ambient temperature. These small mechanical movements can alter the relationship of the CCD pixel position to our predetermined wavelength calibration and would cause the Raman spectral band locations to shift slightly in position with changes in ambient temperature from winter to summer. To address this, we have an auto calibration feature that will automatically trigger a neon calibration of the instrument at predetermined times, providing high-stability Raman systems.
A second feature that can create alterations to the initial calibration is the temporal wavelength stability of the excitation laser. To independently monitor the excitation wavelength, our PROspect software uses the peak position of a known chemical standard in the process stream to automatically adjust the wavenumber calibration to internally correct for any fluctuations that might occur in the wavelength of the excitation laser.

System Stability, 4 Weeks, 7500 Spectra
In a stability study, we tested the system's long-term stability using two different 50/50 toluene-acetonitrile solutions across two separate multiplexer channels. During the study, we evaluated key Raman band parameters: mean position, FWHM, and signal amplitude by fitting each Raman peak to a Gaussian/Lorentzian curve. The study specifically focused on the Raman bands at 786 cm-1 and 1003.5 cm-1 which we observed over the entire four-week period. Our results demonstrated a remarkable standard deviation of just ±0.015 cm-1 in the fitted means, showcasing HORIBA Process Instruments' capability to detect and distinguish minor spectral shifts with exceptional precision.
