A flameless sulfur chemiluminescence detector has also been described (74). The design uses an externally heated ceramic assembly that is operated at low pressme under the necessary fuel-rich conditions but they are out of the flammability limits of hydrogen in air. The hydrogen and air are mixed as the effluent reaches a high-temperature zone. This results in partial oxidation before the effluent reaches the highest temperature zone. It utilizes combustion at low pressure, which is thought to increase the production of sulfur monoxide. The flameless system reduces the effect of column bleed and shows improved detectability over conventional SCD by about one order of magnitude.
