  • Apparatus for near simultaneous chemiluminescent sulfur and nitrogen detection
    Patent number: 6143245
    Abstract: 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 relative 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.
    Type: Grant
    Filed: March 15, 1999
    Date of Patent: November 7, 2000
    Assignee: Antek Instruments, Inc.
    Inventors: Xinwei Yan, Eugene Malcolm Fujinari
