CCQM-P61 Analysis of Volatile Organic Compounds in Solution - Methods, Results, Uncertainties
(2004)
The presentation summarizes the results of the EURAMET key comparison QM-S14 “Measurement capabilities for the quantification of ethanol in water”. Possible options for the key comparison reference value (KCRV) are discussed. A Bayesian approach is finally used to estimate the KCRV and the degrees of equivalence of participants.
The talk presents an analytical method for the quantification of ethanol in water. The method is based on gas chromatography with flame ionisation detection and on-column injection. It is used at BAM for the certification and quality assurance of reference materials for the calibration of evidential breath alcohol analysers.
