[3D04] Development of measurement method of 236U using ICP-MS/MS
Keywords:236U, ICP-MS/MS, radiochemical analysis
We examined the measurement method of 236U using triple-quadrupole inductively coupled plasma-mass spectrometry (ICP-MS/MS, Agilent 8900). The measurable mass to charge ratio (m/z) is expanded up to 275, the device can measure 236U16O16O (m/z = 268) generated by the reaction with O2, which was used as a reaction gas. This mass shift mode decreased the interference from hydride of 235U compared to the previously reported analytical method, which improved limit of detection of 236U using ICP-MS/MS. In this presentation, the optimized measurement condition of 236U measured at m/z = 268 by ICP-MS/MS is reported.
