摘要: The classical isotope dilution approach is adapted for routine element determinations by inductively coupled plasma mass spectrometry (ICP-MS). In the described a calibration graph, which curved definition, used as reference. This graph can be derived both theoretically and practically measuring known concentrations. It shown that deliberately introduced instrumental sensitivity changes are completely corrected for. analytical consequences in terms of curvature blank detection limits discussed.
