In radionuclide metrology three weighing methods could be used for source preparation. The Pycnometer, Elimination and Modified Elimination methods should be compared to evaluate the compatibility in the deposited mass results, so increasing their reliability. In this work, a sequence of micro drop deposition weighing is presented which allows comparing the results by the same drop deposition. The results from each method were determined and their compatibility was checked. As a result, the three methods based on carefully weighing were found compatible and comply with the required threshold uncertainty. Furthermore, it was confirmed the results are traceable to mass the mass unit.
