A Method to Quantify Uncertainty Due to Bias in Chemical Analyses



Raghu N. Kacker


A widely accepted approach to assure that the certified property of a chemical reference material is independent of the method of analysis is to analyze by two or more judiciously chosen methods. The statistical problem then is to determine the consensus value of the measurand and the uncertainty concerning the measurand. This paper describes a new approach to determine the consensus value and the uncertainty. The proposed approach is based on the Guide to the Expression of Uncertainty in Measurement. This approach is not only better than the earlier approaches but it saves cost and time as well.
