EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of TS 8691 test. This standard specifies a method for the determination, by flameless atomic absorption spectrometry, of the vanadium content in gas turbine fuels and household gasolines in the range of 0,4 mg/kg to 4,0 mg/kg.
TS 8691 is a technical specification developed by the International Organization for Standardization (ISO) for the determination of low vanadium levels in liquid fuels using flameless atomic absorption spectrometry after ashing.
Vanadium is a metallic element sometimes found in petroleum products, particularly heavy crudes and residual fuels. Vanadium can cause corrosion and other problems in refinery equipment and can also contribute to polluting emissions when fuel is burned.
The TS 8691 method involves first ashing the fuel sample and then dissolving the remaining ash in acid to remove any organic matter. The resulting solution is then analyzed using a flameless atomic absorption spectrometer, which measures the absorption of light by the vanadium atoms in the sample.
The method is designed to be used for samples containing vanadium at concentrations ranging from 1 to 100 micrograms per liter. The precision and accuracy of the method depends on several factors, including the type of fuel being analyzed and the specific instrument used for the analysis and operating conditions.
Overall, the TS 8691 method provides a reliable and sensitive way to measure low vanadium levels in liquid fuels, which is important for ensuring the quality and performance of these products.
