scope:

This method is for determining hydrocarbon distribution in petroleum naphtha, kerosene (jet fuel), and diesel derived from oxygenated feedstocks such as vegetable or tallow oils in the range of C₃ to C₃₉. Specific components of a boiling point of 85° C (C₆) and less are identified individually. Higher boiling normal paraffins are identified individually, while the non-normals are grouped according to approximate carbon number distribution. The lower limit of quantitation for any compound or grouping is 0.01 mass %. Due to non-normals eluting at n-paraffin sites, the lower limit of quantitation for n-paraffins may not be as low. Components of C₃ and lower molecular weight should not be considered quantitative due to their volatility, see Note. This procedure is not appropriate for analyzing oxygenated feed-stocks prior to the deoxygenation stage in the EcoFining process. Residual oxygenates in feedstocks may not elute from the instrument and are not quantified by this analysis.
