It is demonstrated that this technique gives accuracies in Mg concentrations which are comparable with those of traditional methods, as ICP-OES, in short times and without need for sample preparation. Limits of detection for Mg of the order of 500 ppb are demonstrated. Moreover, a brief discussion about the realization of orooer calibration curves and the definition of the limit of detection （LOD） is reoorted.展开更多
