The use of 99mTc as a tracer in the determination of 99Tc by ICPmass spectrometry
Description
The aim of this paper is to carry out a deep study on the possibilities of using 99mTc from 99Mo-99mTc clinical
isotope generators to trace the radiochemical separations for 99Tc measurements by ICP-MS. By appropriately
de®ning a minimum detectable mass concentration (MDMC) for the mass spectrometer it is possible to
conclude that such use is acceptable for a wide range of activities of the tracer. The MDMC increases from
0.41 to 0.51 ppt when the amount of 99mTc added to the samples ranges from 0 to 2 MBq. The purification of
the final sample from Ru must be the main objective of the 99Tc measurement method, since its presence
noticeably enhances the 99Tc MDMC.
