Thanks to good measurement efficiency (∼6 × 10 –4) and high signal/noise ratio during the analysis, LA-ICPMS can be considered a very promising technique for fast particle analysis, provided that uranium-bearing particles are fixed on the sample holder and located prior to isotope measurement. LA-ICPMS results, although less precise and accurate (typically 10%) than the ones obtained by FT-TIMS and SIMS due to short (20–40 s), transient, and noisy signals, are in good agreement with the certified values or with the results obtained with other techniques. 235U/ 238U ratios were successfully analyzed for all located particles using a nanosecond-UV laser (Cetac LSX 213 nm) coupled to a quadrupole-based ICPMS (Thermo “X-Series II”). Most of the particles were smaller than 1 μm, and their 235U content was in the femtogram range. Prior to the isotopic analysis, particles were precisely located on the disk’s surface by scanning electron microscopy (SEM) for one sample and using the fission track technique for the other sample. Particles were extracted from their initial matrix with ethanol and deposited on a polycarbonate disk where they were fixed in a layer of an organic compound (collodion). The analytical procedure was applied on two particle-containing samples already analyzed in the same laboratory by established techniques for particle analysis: combination of the fission track technique with thermo-ionization mass spectrometry (FT-TIMS) and secondary ion mass spectrometry (SIMS). For the first time, laser ablation–inductively coupled plasma mass spectrometry (LA-ICPMS) was used to carry out isotopic measurement on single submicrometer-size uranium particles.
