Description

1.0 CROSS REFERENCE TO RELATED APPLICATION

[0001] This invention relates and claims priority to U.S. Provisional Patent Application No. 60 / 815,843, filed on Jun. 23, 2006, entitled “Method For The Measurement Of Reactive Molecular Species In Liquid Petroleum And Liquid Petroleum Products”.2.0 BACKGROUND OF THE INVENTION

[0002] 2.1 Field of the Invention

[0003] This invention relates to the detection of reactive molecular species of a chemical element in liquids. More particularly the invention relates to a method and apparatus to detect and quantify reactive molecular species containing a chemical element, such as reactive molecular species containing sulfur, that are potentially present in a liquid, such as gasoline, and react with a material to which the liquid may be exposed, such as silver.

[0004] 2.2 Description of Related Art

[0005] Copper, silver, brass and other “soft metal” alloys are susceptible to corrosion from reactive sulfur molecules. The occasional presence of reactive sulfur ...
