Overcoming ICP-QMS instrumental limitations for Tc-99 determination in environmental solid samples using radiochemistry

Besides its capabilities, quadrupole-based ICP-MS counting establishes several limitations on 99Tc analysis in environmental samples. Overcoming these limitations requires the use of radiochemical methods. We have developed a new method for the detection of 99Tc by ICP-QMS in solid environmental sam...
