The introduction of the laser as an excitation source in Raman spectroscopy offers numerous new possibilities of investigations but demands the design of new types of sample cells specially suited for laser application. Two cells for work with molten salts corrosive to glass and quartz and a simple cell for melts noncorrosive to glass are described. The best results are obtained with a cell which provides total utilization of the laser energy for excitation by multiple reflection of the laser beam. In addition, some necessary accessories for molten salt work, i.e., a gas heater and filtration equipment to free the melt of suspended impurities which might cause an undesirable level of Tyndall and Rayleigh scattering, are mentioned.
