8.3.3 Probe verification
The probe verification wizard may be used to verify that the Raman Rxn2 is performing within specifications. Probe
verification acquires a Raman spectrum of a standard Raman sample, usually 70 % IPA or cyclohexane, and analyzes
the resultant spectrum for peak positions, peak area ratios and Raman signal strength. The peak position verification
confirms that the spectrograph and laser wavelength calibrations are within specification. The peak area ratio
verification confirms that the probe intensity calibrations are within specification. The signal strength verification
confirms that the instrument’s signal-to-noise ratio is within specification. A report is generated showing the results
of the verification steps along with a Pass/Fail indication.
This step is not required to collect a Raman spectrum, but it is highly recommended. Refer to the applicable probe or
optics manual to determine the appropriate verification accessory, acceptable reference samples, and for information
about how to verify the specific analyzer/probe combination.
