Abstract Information :

In the latest, compelling attempt to reduce air pollution, new regulations are being enforced to promote cleaner emissions in passenger vehicles and trucks around the world. In order to stay current with the industry's standards, global fuel refiners are held responsible for monitoring harmful content- such as sulfur and chlorine- in their product. Starting in 2017, barring any last minute revisions, the Environmental Protection Agency (EPA) will be administering new Tier 3 Gasoline Standards in the United States. To adhere to the new EPA requirements set in place, fuel composition must now be limited to a maximum of 10 ppm sulfur content.

ASTM D7220 "Standard Test Method for Sulfur in Automotive, Heating, and Jet Fuels by Monochromatic Energy Dispersive X-ray Fluorescence Spectrometry" can be used to verify your gasoline's compatibility with the new implemented EPA standards. Other types of fuels covered under ASTM D7220 include oxygen-enriched gasoline (RFG), diesel, diesel/biodiesel blends (volume ≤ 20% biodiesel), kerosene, jet fuel, jet fuel/biodiesel blends (volume ≤ 5% biodiesel) and No. 2 home heating oil. The test method's assignment is based off evidence proving that current EDXRF (Energy-Dispersive X-ray Fluorescence) Technology using matrix-matched empirical calibrations can be used for the EPA performance-based testing.

Koehler's EDXRF apparatus adheres to the ASTM D7220 model and has been manufactured to ensure a refiner satisfies the robust regulations associated with the newly enforced Tier 3 Gasoline Standards. Koehler engineered a simple, compact, and versatile benchtop EDXRF analyzer that can detect a substantial array of major and minor atomic elements within a wide variety of samples types, ranging from solids to liquids. The test method's intuitive Silicon Drift Detector's sensitivity can be manipulated with multiple automated tube filters and yields data with superior accuracy. The findings can then be compiled and organized in the complementary software application for concise analysis.

After conducting numerous rounds of laboratory testing, this Koehler's EDXRF instrument has a proven record of accurately measuring the presence of sulfur in various fuel samples. This powerful analytical tool utilizes polarized X-ray technology to accurately determine the sulfur content of the sample in question. When the beam passes through the sample, it reveals the sulfur content after comparing it to a sulfur-free background spectrum.

By using the Koehler EDXRF instrument, refiners can be confident in their continued compliance with the EPA by providing the agency with accurate, reportable data.
