AbstractAnalytical data from a preliminary round robin study on a new method for determining aromatics in distillate fuels are reported. The method was developed by the Combustion and Carbonization Research Laboratory (CCRL) of CANMET, Energy, Mines, and Resources Canada through a private contractor. It applies supercritical fluid chromatography for the separation of total saturates and total aromatics and flame ionization detection for quantitative determination of these hydrocarbons. CCRL proposed to the Canadian General Standards Board (CGSB) that it adopt the supercritical fluid chromatographic (SFC) method as a new standard for determining aromatics in petroleum middle distillates. CGSB commissioned the Committee on Petroleum Test Methods to carry a preliminary round robin study on the proposed method. Results reported in this paper suggest that SFC provides reproducible data among different laboratories and these SFC data correlate well with those obtained from other methods for determining such as fluorescent indicator absorption (FIA), nuclear magnetic resonance (NMR) and mass spectrometry (MS). The American Society for Testing and Materials (ASTM) is currently reviewing a similar SFC method for a new standard. Data indicate that results from the two methods agree well. CCRL requested CGSB to initiate discussions with ASTM for normalization of the two methods.
