Anions in ultrapure water
Analysis for determining the anion content of ultrapure water samples using ion chromatography (IC). The determination of bromide (Br-), chloride (Cl-), fluoride (F-), nitrate (NO3-), nitrite (NO2-), phosphate (PO43-), and sulfate (SO42-) is included in the analysis.
The sample must be collected in a container designed for ultrapure water. We can provide the required sample vessels upon request.
