Determination of actinide elements at femtogram per gram levels in environmental samples by on-line solid phase extraction and sector-field-inductively coupled plasma-mass spectrometry

Isotope ratio analysis of actinides, fission products, and geolocators by high-efficiency multi-collector thermal ionization mass spectrometry

“…Thermal ionization mass spectrometry (TIMS) [72,[108][109][110][111][112], inductively coupled plasma mass spectrometry [113][114][115][116][117][118][119][120], secondary ion mass spectrometry (predominately for particle or surface analysis) [71,54], accelerator mass spectrometry (predominately for high abundance sensitivity analysis) [10,[121][122][123][124], and resonance ionization mass spectrometry (high elemental selectivity) [19,[125][126][127][128] are frequently utilized for analysis of actinides and other radionuclides. Glow discharge mass spectrometry has been used for isotope ratio analysis of actinides, such as uranium [129][130][131], as well as fission-track TIMS for particles [132].…”

Determination of plutonium isotopes in waters and environmental solids: A review

“…An SI manifold furnished with an extraction chromatographic column prior to the detection instrument is illustrated in Fig 4. Truscott et al [124] developed an automated extraction chromatographic method using TRU …”

Modern Strategies for Environmental Sample Preparation and Analysis

“…The in situ method produces dissolved and particulate 137 Cs results, whereas the traditional laboratory method measures total activity in the sample. Truscotti et al (2001) proposes an on-line SPE method for the determination of 232Th, 237Np, 238U, 239pU, 240pU, 241 Am and 243 Am in biological certified reference material using a column TRU-Spec (TM) resin coupled with sector-field ICP-MS.
