Abstract The component mass ratio and moisture of nitrate ester mixtures are crucial technical indicators for the industrial applications and safety performance evaluation. Thus an accurate, fast and simple 1H quantitative nuclear magnetic resonance (qNMR) method was developed for the determination of the component mass ratio and moisture of butanetriol trinitrate (BTTN) and nitroglycerin (NG) nitrate ester mixture simultaneously. By using the NMR ERETIC module technique, the effect of water in solvent and internal standard was eliminated by integral value subtraction method, and the moisture content in BTTN/NG nitrate ester mixture can be accurately calculated. The method enables the determination of component mass ratio and moisture in 10 min of analysis with great linearity (r2≥0.999), high precision (RSD
