Abstract
Method and apparatus are provided for remote in-situ detection and/or monitoring of selected compounds in liquid or gaseous media using one of several methods of Raman spectroscopy. The resulting Raman signal is conducted through optical fibers for recording a Raman spectrum at a distance from the instrument.
