A remote flow cell has been interfaced to a scanning uv‐visible absorbance detector for the detection of gas chromatography (GC) analytes. The unique optical bench, detection scheme, and thermal control allow low‐noise operation at flow cell temperatures of 350 °C. Noise of 1×10−5a.u. (peak to peak over a 1‐min period) and drift at the 1×10−4a.u./h level facilitate detection of coumarin in the gas phase at 40 pg/s. Flow cell volume was optimized for use with capillary GC columns. An effective band pass of <3 nm provides spectral resolution which shows solute absorbance fine structure to aid in compound identification.
