The use of 99mTc as a tracer in the determination of 99Tc by ICPmass spectrometry.0267-94771364-5544http://hdl.handle.net/11441/22783The 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.application/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccesshttps://idus.us.es/xmlui/handle/11441/22783
