Selective Detection with UV Spectroscopy in Gas Chromatography

Using UV spectroscopy as a selective detection approach in gas chromatography (GC) has been demonstrated here with a diode array detector (DAD). The benefits of using an UV detector in GC were realized through effective thermal management and inertness improvement. The approach deployed in this study was proven to be effective for either tandem or parallel detection and has the potential to be used in chromatographic separations that require stringent, narrow bandwidths, such as comprehensive two-dimensional gas chromatography (GCxGC).
