Share link to the free access to a paper that discusses the detailed modelling of the performance of complex measurements in chemistry. https://lnkd.in/eqq5RKw This work proves that detailed “bottom-up” evaluations of the uncertainty of measurement in chemistry involving complex sample preparation are possible. Video: https://lnkd.in/eur9Sei Highlights • Monte-Carlo simulation of isolated sample preparation precision and analyte recovery. • Simulated multimodal between-days component of the relative measurement error. • Mean recovery from the analysis of a CRM and two spiked samples with native analyte. • Fit for purpose uncertainty of total & acid-extractable As determinations in sediment. • Cross-validated uncertainty from randomly selected reference material analyses. #Metrology #Chemistry #AnalyticalChemistry #Uncertainty #Quality #Accreditation
