Determination of the scandium content of high purity titanium using inductively coupled plasma mass spectrometry and glow discharge mass spectrometry as part of its certification as a reference material
Scandium was determined in high purity titanium by inductively coupled plasma mass spectrometry (ICP-MS) and glow discharge mass spectrometry (GDMS). The analysis was carried out as part of the certification campaign for titanium as a neutron dosimetry reference material (NRM 531) from the Institute of Reference Materials and Measurements (IRMM). The scandium concentration in the titanium was found to be less than 2.5 ng/g. This was based on the analysis of four NRM 531 titanium samples. ICP-MS was used with a separation from the matrix by ion exchange. The mean recovery for this separation was 92 %. A comparative measurement by GDMS included a determination of a relative sensitivity factor of scandium in titanium RSF(Sc/Ti) by using four doped titanium samples prepared at IRMM.
