The multi-isotope calibration (MICal) is a fast and accurate calibration strategy for multi-elemental determination that uses only two solutions, (1) 50% (v v?1) sample plus 50% (v v?1) analytical blank solution, and (2) 50% (v v?1) sample plus 50% (v v?1) standard solution (containing the analytes). The calibration curves were built as a function of the intensity signals of solution 1 (y-axis) versus solution 2 (x-axis), employing the various isotopes of each monitored mass/charge. The concentration of the analytes was calculated from the slope and the concentrations of the standards added to solution 2. The validation of the method was evaluated using standard reference materials of bovine liver and bovine muscle. The recoveries varied from 87 to 113% for MICal, which were similar to the conventional standard additions calibration procedure (83 to 120%). |
