AN-CS-019

Trace ammonium and trimethyl-amine in 30% hydrogen peroxide applying sequential suppression


Tóm tắt

Determination of trace levels of cations and amines in hydrogen peroxide is important in quality determination of high-grade semiconductor chemicals. In particular, some manufactures look for 1 ppb trimethylamine or less in hydrogen peroxide samples. Ion chromatography after MiPCT-ME* with conductivity detection after sequential cation suppression is applied.
