RECENT UNPRECEDENTED BIOLOGICAL CHANGES IN ALPINE LAKES RELATED TO ENHANCED DEPOSITION OF ANTHROPOGENIC NITROGEN. TRACE METAL, RADIONUCLIDE AND SEDIMENT ACCUMULATION IN LITTORAL ZONES. CEN radiochronology laboratory also offers Pb-210 dating.Pb against depth or cumulative weight (to allow for compacting) will be a straight line if the sedimentation rate has been constant.Least squares regression is used to determine the slope of the decay curve, from which the sedimentation rate can be calculated. We are proud of our reputation and strive to provide quality service to ensure that every project is successful for our customers.
We are using the AMS method (Accelerator Mass Spectrometry). C-H-N analyses are also available now (possibility to get the percentages of C (Carbon), H (Hydrogen) and N (Nitrogen) for dry samples.
The analyses are processed with a Leco CHN628 elemental analyzer.
