COMMISSION ON ISOTOPE SPECIFIC MEASUREMENTS AS TRACEABLE
Title: Establishing International Comparability of Measurements
of Trace Elements in Natural Water (IMEP-6)
Series: International Measurement Evaluation Programmes
Lamberty and J.R.
Remarks: Division V and Section VII.C
Completion Date: 1998 - Project Completed
The measurement of water quality is of paramount importance to
human health. Despite being a theoretically easy matrix to analyze,
water analyses are often in wide disagreement among laboratories.
The IMEP-6 programme examined water analytical data quality on a global
scale using certified test samples with reference values determined
by a primary method of measurement (isotope dilution mass spectrometry).
More than 150 participants were involve in the programme. The
reference values for 14 elements in natural and artificial water were
established by the cooperation of 4 national laboratories in 3 countries.
