Abstract

We report on a specially designed setup which combines the advantages of Raman difference spectroscopy with the multiplex advantages of multichannel detection. The new device and the principle of operation are described in detail. Several examples of Raman difference spectra are shown to demonstrate the performance of the setup. Static as well as scanning multichannel techniques were applied to test the distinct capabilities of the system. Both methods are discussed with special emphasis on the reliability and accuracy of the results obtained.
