    1. Scope

    1.1 Elemental analysis tests form an important of quantifying the product quality in the oil industry. Most published test methods are based on their applicability to petroleum products and lubricants. However, as an important sector of biofuels both biodiesels and fuel-ethanol becomes important the test methods once used for petroleum products need to be reviewed for biofuels to assure that they work equally well for these new fuels. 1.2 There are a number of tests used for analysis of biofuels that may not have the same level of precision as that obtained for petroleum products. There could also be interferences from some constituents of biofuels in the ultimate measurements. On the other hand, there are several methods which apply to biofuels without any change in them. Some others have been specially drafted for biofuels. 1.3 This Guide summarizes the information about the tests methods for elemental analysis of biofuels. It is hoped that this information will be useful to both product specification writers and laboratory users. Areas where further work needs to be carried out for definitive elemental analysis are also identified.

    3.1 Biofuels are increasingly becoming an important alternative to traditional fossil fuel based energy sources. Although a number of biofuel specifications have been formalized, for many of these matrices the analytical test methods quoted in these specifications remain largely untested. These test methods were originally devised for the analysis of petroleum and petroleum products, and their utility and precision for application to biofuels is largely not known. 3.2 This Guide summarizes the test methods used in the biofuel specifications for elemental analysis and discusses their applicability to these matrices.
