CHEMICAL SEPARATION AND PLURAL-POINT, SURFACE-ENHANCED RAMAN SPECTRAL DETECTION USING METAL-DOPED SOL-GELS

摘要

Amethod and apparatus for substentially simultaneous separating and dectecting 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) as depicted on figure 4.
