Chevron’s "Motor Gasolines Technical Review”

Visit the Chevron site and browse the “Motor Gasolines Technical Review” (March 2008) to glean some useful desulf nuggets. One such nugget is a listing of all the ASTM standards pertaining to testing for sulfur content …

Sulfur Content
ASTM D 1266 – Test Method for Sulfur in Petroleum Products (Lamp Method)
ASTM D 2622 – Test Method for Sulfur in Petroleum Products by X-Ray Spectrometry
ASTM D 3120 – Test Method for Trace Quantities of Sulfur in Light Liquid Hydrocarbons by
Oxidative Microcoulometry
ASTM D 4045 – Test Method for Sulfur in Petroleum Products by Hydrogenolysis and Rateometric
Colorimetry
ASTM D 4294 – Test Method for Sulfur in Petroleum and Petroleum Products by Energy-Dispersive
X-ray Fluorescence Spectrometry
ASTM D 5453 – Test Method for Determination of Total Sulfur in Light Hydrocarbons, Motor
Fuels and Oil by Ultraviolet Fluorescence
ASTM D 6334 – Test Method for Sulfur in Gasoline by Wavelength Dispersive X-Ray Fluorescence
ASTM D 6445 – Test Method for Sulfur in Gasoline by Energy-Dispersive X-ray Fluorescence
Spectrometry

As the sulfur test method names indicate, there are several technologies used to determine the sulfur content of gasoline. Some of the methods are applicable only to high sulfur levels, others cover a broad range, and some can be used only for low sulfur levels. Specific test methods need to be reviewed for applicability before selecting one to use.
