Scientific paper

Using classical methods of assay analysis for highly concentrated rocket grade hydrogen peroxide (RGHP, H2O2), comparison and correlation to historical values using currently available commercial-source RGHP is presented. In particular, fluid densities, refractive index, and the potassium permanganate (KMnO4) wet chemical method of analysis are compared. Discussion includes those analytical processes that support field use, with attendant rapid, accurate, and verifiable concentration determinations of RGHP. Method accuracy is ranked as Manual KMnO4 Titration > Refractive Index > Density, based on vendor certifications, with the refractive index method having best precision (+/-0.02%wt H2O2). Results from densitometry data are anomalous, with variability likely due to less mature measurement techniques used in this study.
