Chemical analysis with a low-resolution Raman spectrometer

The performance of a very compact and low-cost Raman system has been examin ed in detail. We have attempted to use it for both qualitative identificati ons and quantitative analyses of mixtures. As a part of the evaluation, wt have attempted to devise compensation routines when these were needed. We c onclude that this system can be used for a limited range of qualitative app lications, but that the quantitative performance is inadequate. The princip al problems originated in laser fluctuations and in the appearance of spect ral artifacts when the laser was operated.
