Abstract:
1. A thermo-electrically cooled surface enhanced Raman spectroscopy sensor system, comprising: a source for providing an inert gas; a manifold having a semipermeable membrane for separating moisture from an analyte wherein said analyte and said inert gas mix to create a gas mixture; a chamber body having a sample chamber for receiving said gas mixture; a SERS structure is positioned in said sample chamber, an optical energy source for generating an optical excitation signal that irradiates said SERS structure; a spectroanalysis system for detecting optical emissions generated in response to said SERS structure being irradiated by said optical excitation signal when said analyte is in contact with said SERS structure; and a drying chamber for removing moisture from said gas mixture.
