Determination of trimenthylamine and standard cations in 30% hydrogen peroxide (H2O2)

Hydrogen peroxide is available in different purity grades depending on its use. High purity H₂O₂ (electronic grade) requires very low contamination levels, e.g., less than 1 μg/L of trimethylamine (TMA). This application describes the determination of trimethylamine in a high-purity H₂O₂ solution (30%). Analysis is performed using Inline Preconcentration with Matrix Elimination (MiPCT-ME) applying conductivity detection after sequential cation suppression.
