Abstract

The Institute for Reference Materials and Measurements is conducting on a regular basis an International Measurement Evaluation Program (IMEP) aimed at displaying the real state of the practice in measurements of toxic and life essential metals. The programme offers certified ranges (conservative uncertainties obtained by means of isotope specific methods).

The IMEP-6 program, Trace metals in synthetic and natural water, with 165 participants from 29 countries, is currently being evaluated. The work presented describes the certification of rubidium in the two water samples involved. Special attention is given to the various sources of uncertainty present. Figures will be presented picturing the state of the practice in the determination of total rubidium concentrations, at low parts per billion levels, among the participating laboratories. .
