title: Concentration measurements of sucrose and sugar surfactants solutions by using the 1H NMR ERETIC method.
abstract: The ERETIC method has been used to determine precise concentrations of aqueous solutions of sucrose and sugar surfactants, namely octyl glucoside and fatty acid sucrose esters by (1)H NMR spectroscopy. The effects of NMR tuning, acquisition parameters, and spectrum processing on the measurement have been assessed in these particular cases. The linearity upholds over the whole concentration range, with both sucrose and octyl glucoside, whatever the physicochemical phenomena occurring, either an increasing viscosity or the micellization of the surfactant. For sucrose solutions, an accuracy of 2% is measured for concentrations between 0.1 and 200 mmol/L, which is consistent with literature data.
