Raman and absorption spectroscopy instrumentation will be used in various labs at Howard T. Rickets Laboratory to determine the chemical and physical properties of samples by monitoring the interaction of light with the samples. Samples will be returned to customers (unaltered) after analysis. Samples may be in the gas, liquid, or solid phase, are generally analyzed in their original state, and returned to the customer for disposal.
