In-situ Sample Preparation for Radiochemical Analyses of Surface Water
A new method for radionuclide sample analysis of surface water has been demonstrated at the Savannah River Site, a U.S. Department of Energy manufacturing facility, currently in standby. The method makes use of selective solid phase extraction (SPE) disks being placed in a modified portable aqueous sampler. The analytes currently measured by this in-situ preparation are Tc, Sr, Cs and Co. The S...
متن کاملOptimal Sample Preparation for the Analysis of Micrometric Heterogeneous Samples.
Precise microanalytical techniques are essential in many fields such as cultural heritage materials, showing complex layered microstructures containing a wide range of materials of diverse nature and hardness. Noninvasive sample manipulation and preparation is required to avoid, as much as possible, sample contamination, which may strongly limit the materials identification. The method proposed...
