IAEA-TERC-2023-01/02 World Wide Open & ALMERA Proficiency Test Exercise / 7.12.2023
Agilent 8900 triple quadrupole ICP-MS was used for the first time in a proficiency test for 90Sr analysis, a field that is typically dominated by radiometric methods.
To achieve a higher degree of quality assurance, it is important to participate in proficiency tests administered by an internationally acknowledged reference laboratory. To meet this requirement, our laboratory took part in the IAEA-TERC-2023-01/02 World Wide Open & ALMERA proficiency test exercise organized by the International Atomic Energy Agency (IAEA). Agilent 8900 triple quadrupole ICP-MS was used for the first time in a proficiency test for 90Sr analysis, a field typically dominated by radiometric methods.
The outcomes of this work indicate that our scientific efforts to widen the analytical capabilities of inorganic mass spectrometry have been successful.
This is the first time that an ICP-MS (Agilent 8900 triple quadrupole mass spectrometer) method met the criteria for a proficiency test in quantifying 90Sr at an environmental level.
This newly developed method is very competitive with traditional radiometric methods regarding accuracy, precision, and detection limit. The implementation of accreditation and regular use of this method is anticipated soon, resulting in a substantial reduction in the time required for 90Sr measurement.
