A new milestone for ultra-low ²³⁶U/²³⁸U isotope ratio measurements by ICP-MS/MS

Abstract

Uranium isotope composition in environmental samples allows to trace its origin. Therefore, the analytical community has been working for several years to reduce the detection limit of the 236U/238U isotopic...

Direct determination of 237Np in nuclear effluent by ICP-MS/MS

“…, O 2 , NO 2 …) has proven its efficiency to form uranium oxides (UO and UO 2 ) and to significantly decrease uranium polyatomic interferences such as hydrides. 20…”

“…, 235 U, 236 U and 238 U). 17–20 In fact, the MS/MS mode drastically decreases the overlap of the uranium 238 peak with the neptunium 237 peak due to the abundance sensitivity performance (<10 −10 ). 21 Studies using collision reaction cell (CRC) capabilities to eliminate hydride interferences ( e.g.…”

Atomic spectrometry update: review of advances in atomic spectrometry and related techniques

“…Jaegler and Gourgiotis 174 utilised an ICP-MS-MS technique with the aim of improving the detection limit of 236 U/ 238 U. Advances in the ion transmission and the range of measurable signals, coupled with desolvation-nebulisation and a reaction cell primed with oxygen provided the potential for the determination of low levels of 236 U.…”
