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 g/L (ppb) in
less than 15 minutes.
