ASTM D7328 : 07

Standard Test Method for Determination of Total and Potential Inorganic Sulfate and Total Inorganic Chloride in Fuel Ethanol by Ion Chromatography Using Aqueous Sample Injection

Standard Details

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.
