Compositions, methods of use and systems for analysis of silicon levels in petroleum materials

摘要

This invention relates in general to the determination of silicon levels in fuel mixtures, such as petroleum products. More particularly, the present invention relates to compositions for use as standards in an x-ray analyzer for the measurement of silicon in various fuel mixtures, and to methods of using these compositions.

主权项

1. A method of measuring silicon in a fuel mixture comprising:
a. providing a composition comprising a solution of about 0.5% to 3.0% wt. % total of one or more organosiloxanes substantially free of elements other than silicon, oxygen, carbon and hydrogen, having a boiling point between 35° C. and 375° C., in an organic solvent having a boiling point between about 64° C. and 125° C., wherein the solvent is substantially free of elements other than oxygen, carbon and hydrogen, wherein said organosiloxane has a boiling point matched to within the boiling point range of said fuel mixture; b. calibrating an X-ray silicon analyzer with said solution; c. providing said fuel mixture to said X-ray silicon analyzer; and d. measuring the silicon concentration in said fuel mixture.
