AU155: Determination of Cations and Amines in Hydrogen Peroxide by Ion Chromatography Using a RFIC (Reagent-Free) System
![determination cations hydrogen peroxide](/Image/AppImage/2181/20210323181738/determination-cations-hydrogen-peroxide?imageNameOnDisk=2181.jpg)
Description
Hydrogen peroxide is an essential chemical in the fabrication of integrated circuit and microcircuit devices. Maximum allowable contaminate levels for semiconductor grade hydrogen peroxide can be as low as <100 ppt (ng/L) per individual inorganic cation. This application uses an IonPac CS17 column to determine trace cations and amines in hydrogen peroxide with a large-loop injection. The CS17 column separates amines without the organic solvent eluent modifier needed for separating amines when using older cation-exchange ion-chromatography (IC) columns.Market: | Chemical |
