    Abstract
  • The measurement uncertainty for the analytical results of cdmium in groundwater samples by inductively coupled plasma-mass spectrometry (ICP-MS) was evaluated using Continuous Propagation Model of Uncertainty. The main sources of measurement uncertainty came from sub-uncertainties of calibration solutions, calibration curve fitting and measurements. The double-error regression was used in the course of standard curve fitting. The overall uncertainty of measurement results was obtained from the synthesis of sub-uncertainties.
