  • Page 39: Operation

    Operating Instructions Operation WARNING  Whenever the Raman Rxn4 analyzer main power switch and laser key are in their ON position, probes should be shuttered or covered, or remain immersed in the sample to be measured. Raman RunTime embedded software Raman RunTime is the embedded control software installed on all the Raman Rxn4 analyzers.

  • Page 40: Calibration And Verification

    Probe calibration The sensitivity of the Raman Rxn4 varies with wavelength due to variations in the throughput of the optics and the quantum efficiency of the CCD. The probe calibration function in Raman RunTime can be used to remove the effects of this variation from measured spectra.
  • Page 41 8.3.3 Probe verification The probe verification wizard may be used to verify that the Raman Rxn4 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.
