ABSTRACT:
An improved method and apparatus for the measurement of sulfur compounds is described. The system comprises a dual burner assembly for the conversion of sulfur-containing compounds to form sulfur monoxide and subsequent detection of sulfur monoxide by ozone-induced chemiluminescence. The dual burner assembly also provides for the conversion of hydrocarbons and other chemical constituents of the sample to simple molecules that do not interfere in the formation or detection of sulfur monoxide. The dual burner assembly eliminates the interference observed in the measurement of sulfur compounds from the sample matrix using flame-based or single burner devices for the production of sulfur monoxide and detection by ozone-induced chemiluminescence.
