Abstract:
Using quartz as the basis of SCD (Sulfur Chemiluminescence Detection) combustion tubes was reexamined, primarily aimed at improving detector performance. Research focused on the Agilent model 8355 but is applicable to other versions and competitive models. From early SCD development, quartz was used as a combustion material but suffered from an unknown high background, among other issues. The author now believes the background is due to the formation of silicon monoxide. Evidence to support this will be presented. The high background problem has been solved with the use of hybrid materials, resulting in better stability and consistency among combustion tubes.
