Dual Plasma Burner
The Dual Plasma Burner consists of a tower assembly that contains an outer sheath for burn protection, a heating element, thermocouple, and combustion tubes. In the SCD, conversion of sulfur containing compounds to SO occurs within the ceramic reaction chamber housed in the Burner assembly and potentially interfering hydrocarbons are oxidized to CO2 and H2O, with air as the oxidant. In the NCD, oxygen is used as the oxidant.
A fitting is located on top of the Burner. The vacuum line from the Detector box is connected directly to the top of this fitting and H2 is input to the longer side of this fitting. The air inlet is connected to the base of the Burner.
The Burner is mounted onto the GC by a
