AB - A diode-laser-based portable Raman spectrometer is described that uses a 2-dimensional-array detector (charge-coupled device--CCD) to simultaneously measure chemical processes at several remote points using fiber optics. Optical multiplexing with the CCD allows simultaneous measurements with little loss of sensitivity and the low-energy near-visible (NVIS) excitation (e.g., 786 to 820 nm) prevents most sample luminescence. Several fiber- optic sensor configurations optimized for particular applications, including surface-enhanced Raman (SER), are presented. Applications are described including in-situ epoxy cure chemistry monitoring in a curing oven, monitoring a distillation apparatus, and mixed waste monitoring. Some of the limitations of the system are discussed.
