The Waters Alliance HPLC System, with the Waters Two-Position Six-Port Switching Valve, coupled to the Waters 2414 Refractive Index Detector, is shown to greatly exceed the performance requirements for the application of the ASTM D6591 (IP548) standard method for the determination of aromatic hydrocarbons in middle distillates. The instrument set up demonstrates compliance with the ASTM standard method, meeting the linearity, resolution, and precision criteria, with calibration coefficients that demonstrate an excellent linear response for quantification of aromatic hydrocarbons.
