Surface-Enhanced Raman Spectroscopy as a Detection Method in Gas Chromatography
Abstract:The use of surface-enhanced Raman scattering (SERS) as a detection method in gas chromatography (GC) was investigated by two different approaches; GC eluates were trapped either in liquid silver sol or on solid thin-layer chromatography (TLC) plates, previously coated with silver colloidal solution. Subsequently, the trapped analytes were monitored by their SERS spectrum. Pyridine was successfully used as probe molecule for both interfaces. The extension of this static system for application in on-line detection of GC eluates is discussed.
