本文参照ASTM D7328对变性乙醇燃料样品进行前处理后，选用高容量 IonPac AS22高效阴离子交换分离柱完成了样品中痕量游离氯化物和硫酸盐及 总硫的含量测定。方法选择性较好，氯离子和硫酸盐的分离不受样品基质的 影响，其定量结果更加准确。

This method shows the direct determination of potential chloride and sulfate in a peroxide-treated denatured ethanol sample, previously published in Application Update 194. In this record, the method is executed on an Integrion IC system.

This record shows a 5-min, fast separation of anions in a municipal drinking water sample on the 4µm resin particle format IonPac AS22-Fast-4µm column. This method upgrades Application Brief AB120 by improving the separation using the 4µm resin particle column to produce more efficient peaks. The Integrion ion chromatography system is designed to work with the high pressures generated by the 4µm particles to deliver the improved separation.

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.
