AU161: Determination of Sulfate and Chloride in Ethanol Using Ion Chromatography
Description
This application is an improved method for determining sulfate and chloride in ethanol using IonPac AS22 column and carbonate/bicarbonate eluent. In this method, the AS Autosampler performs a direct inject on a TAC-ULP1 anion concentrator, installed in place of the injection loop, and then washes off the ethanol. This method allows the use of electrolytic suppression in the recycle mode for the highest level of convenience and good sulfate stability even when 20 mg/L of sulfate is spiked into gasoline- denatured ethanol. The method determines if the ethanol meets ASTM Specification D 4806.| Market: | Petrochem, Oil and Gas |
