Determination of pyrophosphate and standard anions in 30% hydrogen peroxide (H2O2)
AN-S-352

<p>Pyrophosphate is used as a stabilizer in aqueous hydrogen peroxide solution. “Reagent grade” solutions may contain pyrophosphate in the higher mg/L range, while “electronic grade” hydrogen peroxide should be free of this stabilizer. Here the determination of pyrophosphate in a high purity H<sub>2</sub>O<sub>2</sub> solution (30%) is performed applying Inline Preconcentration with Matrix Elimination (MiPCT-ME) and a Dose-in Gradient.</p>
