Article presents normalized analytical methods for determination of elements in fuels and biofuels with emphasis on inductively coupled plasma emission spectrometry (ICP-OES) and their advantages and disadvantages. Analytical procedure applied for determination of 20 elements (Al, B, Ba, Ca, Cr, Cu, Fe, K, Mg, Mn, Mo, Na, Ni, P, Pb, Si, Sn, Ti, V and Zn) is described with elements of validation. Broad range of elemental analysis results of fuels (B0, B7 and B10) and pure FAME samples are described. Typical contents of selected elements are presented which allows discussion on the domestic fuel quality in regard to non-standardized parameters and their potential effect on combustion engines performance.

Abstract A modification of an inductively coupled plasma (ICP) emission spectrometer is described that enables the simultaneous determination of nitrogen, phosphorus, and potassium in water-soluble fertilizers. A quartz extension tube is added to the ICP torch to exclude air from the plasma, thus allowing accurate nitrogen determination without adversely affecting sensitivity for other analytes. The modification also requires an 18 mg/L argon coolant flow to protect the tube from the heat of the plasma. Detection limits are 20 mg/L for nitrogen and 50 μg/L for phosphorus and potassium. Three NBS reference salts and 2 commercially available fertilizers were analyzed by the method, and results are in excellent agreement with known values.
