ASTM D4294

Standard Test Method for Sulfur in Petroleum and Petroleum Products

ASTM D4294 is a standard test method for the determination of total sulfur in petroleum and petroleum products by energy dispersive X-ray fluorescence spectrometry (EDXRF). It is a rapid and precise method that can be used to measure the sulfur content of a wide range of petroleum products, from diesel fuel to jet fuel to lubricating oils.

Sulfur is an undesirable element in petroleum products because it can contribute to air pollution. The amount of sulfur in petroleum products is regulated by government agencies in many countries. ASTM D4294 is used by petroleum refineries, environmental testing laboratories, and government agencies to ensure that petroleum products meet the required sulfur limits.

Here are some of the reasons why ASTM D4294 is important:

  • It is a reliable and accurate method for determining sulfur content
  • It is an internationally accepted test method, enabling trusted determination of one of several fuel parameters for easy trading and transportation of fuels
  • It is a rapid method, so it can be used to test a large number of samples quickly
  • It is a cost-effective method
  • It is a versatile method that can be used to test a wide range of petroleum products

ASTM D4294 Instrumentation

Our Epsilon 1 Sulfur in Fuels, Epsilon 1 for Ultra Low Sulfur, and Epsilon 4 Oils & Fuels instruments are all compliant with ASTM D4294, a standard test method for the determination of total sulfur in petroleum and petroleum products by energy dispersive X-ray fluorescence spectrometry (EDXRF).

The Epsilon 1 Sulfur in Fuels instrument is designed for the analysis of fuels with a sulfur concentration of 16 ppm or higher. 

The Epsilon 1 for Ultra Low Sulfur instrument is designed for the analysis of fuels with a sulfur concentration of 5 ppm or higher. Even in the presence of high levels (up to 5%) of Sulfur

The Epsilon 4 Oils & Fuels instrument is a laboratory XRF instrument that is even more powerful with the lowest detection limits in the Epsilon series and can be used to analyze a wide range of petroleum products, including fuels, oils, and lubricants.

All of these instruments are in compliance with ASTM D4294. They also offer a number of other advantages, such as:

  • Fast and precise analysis
  • Minimal sample preparation
  • No need for helium
  • Low running costs

The Epsilon 1 Sulfur in Fuels, Epsilon 1 for Ultra Low Sulfur, and Epsilon 4 Oils & Fuels instruments are used by a variety of industries, including petroleum refining, fuel supply, environmental monitoring, and research. These instruments are helping to ensure that the sulfur content of petroleum products is within the limits set by government regulations, which helps to protect the environment and human health.
