ABSTRACT:
A sensor for performing surface enhanced Raman spectroscopy comprises: a) a sensor body having a throughbore; an optical energy source for generating an optical excitation signal; b) a surface enhanced Raman scattering structure that is mounted to the sensor body through which the optical excitation signal is directed for irradiating an analyte, whereupon the analyte generates primary Raman emissions in response to being irradiated by the optical excitation signal, and wherein the surface enhanced Raman scattering structure generates secondary Raman emissions when irradiated by the optical excitation signal; c) an optical detector for generating an output signal that represents the spectral characteristics of the primary and secondary Raman emissions in response to receiving the primary and second Raman emissions; and d) a processor for substantially filtering the secondary Raman emission from the primary Raman emissions and for generating an output signal representing the analyte.
