AU194: Determination of Existent and Potential Sulfate and Total Inorganic Chloride in Denatured Ethanol by Direct Injection Using an RFIC System

Instrument Type: IC

According to American Soceity for Testing and Materials (ASTM) Standard D4806-13a, the concentrations of chloride and sulfate in denatured fuel ethanol used as a blending agent in gasoline are required to be <40 mg/L and <4 mg/L, respectively. This application describes an improved method for determination of total inorganic chloride as well as existent and potential sulfate in denatured ethanol using an RFIC system.
