Popis:	A simple high voltage ac spark produced between tungsten electrodes in both nitrogen and argon atmospheres is investigated as an emissive detector for certain organic molecules. Volatile vapours entering the electrode gap lower the resistance and an increased current flows in the spark. The energy available, particularly using nitrogen as a carrier gas, is sufficient to excite UV/visible spectra for various organic compounds; carbon species may be detected at 389 nm (CN), sulphur compounds at 257 nm (CS), halogenated compounds at various tungsten atomic lines and iodine at 206.2 nm (iodine atomic).
