SIMULTANEOUS CHEMICAL SEPARATION AND SURFACE-ENHANCED RAMAN SPECTRAL DETECTION USING METAL-DOPED SOL-GELS

摘要

A method and apparatus for substantially simultaneous separating and detecting analytes by Raman spectroscopy is disclosed. The apparatus comprises a channel (28) containing at least one metal-doped surface-enhanced Raman-active sol-gel. The analytes are introduced through an inlet (21) and are detected with a Raman probe (34).
