On Oct 24, 2013 a seminar “Quality assurance and validation of analytical methods in the laboratory” was organized jointly in helsinki by the Finnish Chromatography society and Finnish Mass spectrometry society. Ivo Leito from University of Tartu made a presentation on the approaches to measurement uncertainty estimation. The presentation compared the ISO GUM modelling and the Nordtest approach to measurement uncertainty estimation. The Nordtest approach was explained in more detail and an application example – measurement uncertainty in LC-MS analysis (determination of acrylamide in snacks by LC-MS) – was discussed. The online course of measurement uncertainty estimation in analytical chemistry that was recently set up at University of Tartu was briefly introduced.
