This application note describes a rapid, high-volume, direct-injection technique that utilizes an IonPac® AS14 2-mm analytical column and a borate eluent with a step change. The separation was applied to high-purity water as well as amine-treated matrices of interest to the power generation industry. Common anions such as fluoride, chloride, nitrate, phosphate, and sulfate were determined at levels below 1 μg/L (ppb) in less than 15 minutes.
