International standards for sulfur measurement
Eraly & Associés designs and manufactures analyzers and accessories that meet the performance criteria of international standards for Total Sulfur measurement in numerous compounds and products.
ASTM D5453
Standard Test Method for Determination of Total Sulfur in Light Hydrocarbons, Spark Ignition Engine Fuel, Diesel Engine Fuel, and Engine Oil by Ultraviolet Fluorescence.
This test method is applicable to naphthas, distillates, engine oil, ethanol, Fatty Acid Methyl Ester (FAME), and engine fuel such as gasoline, oxygen enriched gasoline (ethanol blends, E-85, M-85, RFG), diesel, biodiesel, diesel/biodiesel blends, and jet fuel. Samples containing 1.0 mg/kg to 8000 mg/kg total sulfur can be analyzed.
ASTM D7183
Standard Test Method for Determination of Total Sulfur in Aromatic Hydrocarbons and Related Chemicals by Ultraviolet Fluorescence.
This test method is applicable to samples with sulfur concentrations to 10 mg/kg. The limit of detection (LOD) is 0.03 mg/kg S and the limit of quantitation (LOQ) is 0.1 mg/kg S.
ASTM D6667
Standard Test Method for Determination of Total Volatile Sulfur in Gaseous Hydrocarbons and Liquefied Petroleum Gases by Ultraviolet Fluorescence.
Precision has been determined for sulfur in gaseous hydrocarbons in the range of 1 mg/kg to 100 mg/kg and for sulfur in LP gases in the range of 1 mg/kg to 196 mg/kg.
ASTM D 7551
Standard Test Method for Determination of Total Volatile Sulfur in Gaseous Hydrocarbons and Liquefied Petroleum Gases and Natural Gas by Ultraviolet Fluorescence.
sulfur in the range of 1 to 200 mg/kg.
IP 490
Determination of sulfur content of automotive fuels - Ultraviolet fluorescence method.
- products having sulfur contents in the range 3 mg/kg to 500 mg/kg,
- motor gasolines containing up to 3,7 % (m/m) oxygen [including those blended with ethanol up to about 10 % (V/V)],
- diesel fuels, including those containing up to about 30 % (V/V) fatty acid methyl ester (FAME),
- products having sulfur contents in the range of 3 mg/kg to 45 mg/kg,
- synthetic fuels, such as hydrotreated vegetable oil (HVO) and gas to liquid (GTL).
ISO 20846
Petroleum products — Determination of sulfur content of automotive fuels — Ultraviolet fluorescence method.
- Product having sulfur contents in the range 3 mg/kg to 500 mg/kg.
- Motor gasolines containing up to 3,7 % (m/m) oxygen [including those blended with ethanol up to about 10 % (V/V)].
- Diesel fuels, including those containing up to about 30 % (V/V) FAME.
- Having sulfur contents in the range of 3 mg/kg to 45 mg/kg.
- synthetic fuels, such as hydrotreated vegetable oil (HVO) and gas to liquid (GTL).
SH/T0689
Standard test method for determination of total sulfur in light hydrocarbons, motor fuels and oils by ultraviolet fluorescence.
This standard applies to the total sulfur content of 1. 0 ~ 8000mg/kg naphtha, distillate oil, fuel and other oil products.
UOP 987
Low Trace Sulfur in Liquid Hydrocarbons by Oxidative Combustion with Ultraviolet Fluorescence Detection.
This method is for determining sulfur in liquid hydrocarbons at concentrations ranging from 10 to 1500 ng/g (mass-ppb). A direct measurement procedure (Part A) is used for samples above 100 ng/g. A trap & release procedure (Part B) is used for samples between 10 and 200 ng/g where high precision is required. This method is also applicable to highly volatile samples, such as pentane, through the use of a cooled sampling system.
