Abstract
A spreadsheet application is developed for the prediction and optimization of the analytical performance of instrumental neutron activation analysis for matrices of more or less known composition. It assists in feasibility testing, sensivitity enhancement and cost reduction.
Abstract
The concepts of the Guide to the expression of Uncertainties in Measurements for chemical measurements (GUM) and the recommendations of the Eurachem document "Quantifying Uncertainty in Analytical Methods" are applied to set up the uncertainty budget for k 0-NAA. The "universally applicable spreadsheet technique", described by Kragten, is applied to the k 0-NAA basic equations for the computation of uncertainties. The variance components — individual standard uncertainties — highlight the contribution and the importance of the different parameters to be taken into account.
