AU139: Determination of an Anionic Fluorochemical Surfactant (FC-95) in a Steel Bath
Description
This Application Update describes a method for determining low ppm amounts of FC-95 in a steel bath (concentrated hydrofluoric, hydrochloric, and nitric acids with 200 g/L each of iron, chromium, and nickel) by ion chromatography. The method described in this Update is similar to that described in AN 119. The surfactant is removed from the acidic matrix and concentrated on an IonPac® NG1 column. The concentrated surfactant is then eluted from the IonPac NG1 column onto an OmniPac PAX-500 column set and detected by suppressed conductivity.| Market: | Chemical |
