High-Performance Dual Raman Spectrometer

Abstract

The transformation of an old Raman double monochromator into a dual spectrometer capable of working either as the original instrument or as a very high sensitivity scanning single monochromator with multichannel charge-coupled device (CCD) array detection is described. The merits and limitations of this instrument, particularly suited for medium/low resolution (0.3 to 2 cm−1) Raman spectroscopy in the gas phase, are discussed. Example spectra of O2, N2, CO2, H2O, and CCl4 are shown.
