Additional information

1. Scope

1.1 This test method covers an ion chromatographic procedure for the determination of the total and potential inorganic sulfate and total inorganic chloride content in hydrous and anhydrous denatured ethanol to be used in motor fuel applications. It is intended for the analysis of ethanol samples containing between 0.55 and 20 mg/kg of total inorganic sulfate, 4.0 to 20 mg/kg of potential inorganic sulfate, and 0.75 to 50 mg/kg of total inorganic chloride.
