A method and apparatus are disclosed for the near simultaneous detection of light emitted from ozone induced chemiluminescence of nitrogen and sulfur species capable of undergoing ozone induced chemiluminescence in a single instrument. A sample containing sulfur and/or nitrogen is first subjected to an oxidative/reductive process which generates ozone reactive nitrogen and sulfur species which are then forwarded to an specially designed ozone/detector chamber. The ozone reactive species are brought in contact with ozone in the special chamber and the chemiluminescence of the nitrogen species and the sulfur species are measured and quantitated.
