“…The detection limits is estimated that the 235 U amount of 4.5 fg is sufficient to obtain the 235 U/ 238 U ratio with the relative standard deviation (RSD) within 5.0%, the 234 U amount of 0.42 fg and the 236 U amount of 1.1 fg are sufficient to obtain the 234 U/ 238 U and 236 U/ 238 U ratios with the RSD within 20%, respectively [13]. In recent years, some combination methods for improving the measurement precision and detection limit of uranium isotope abundance ratios [5,14,15]. Although these developed techniques enabled to acquire stable signals needed for isotope ratio measurement, there is a difficulty in analyzing 234 U/ 238 U and 236 U/ 238 U isotope ratios accurately because of isobaric interferences caused by molecular ions of other elements.…”

“…A second report by Esaka et al . () describes an alternative particle search strategy based on an initial identification using fission track observations of irradiated particles contained in a polycarbonate film. Particles enriched in uranium, as determined by the presence of fission tracts in the etched polycarbonate, along with 25 μm of the surrounding film, were extracted from the sample.…”

Advances in the chemical and isotopic characterisation of geological and environmental materials can often be ascribed to technological improvements in analytical hardware. Equally, the creation of novel methods of data acquisition and interpretation, including access to better reference materials, can also be crucial components enabling important breakthroughs. This biennial review highlights key advances in either instrumentation or data acquisition and treatment, which have appeared since January 2010. This review is based on the assessments by scientists prominent in each of the given analytical fields; it is not intended as an exhaustive summary, but rather provides insight from experts of the most significant advances and trends in their given field of expertise. In contrast to earlier reviews, this presentation has been formulated into a unified work, providing a single source covering a broad spectrum of geoanalytical techniques. Additionally, some themes that were not previously emphasised, in particular thermal ionisation mass spectrometry, accelerator‐based methods and vibrational spectroscopy, are also presented in detail.

“…After etching, relocate uranium-bearing particles under the optical microscope with the aid of the locations of marks and tracks so as to identify the particles. Fumitaka Esaka et al [11] put forward another fission track method to identify uraniumbearing particles: putting particles into the PC solution, dropping the solution with particles on the quartz sheet to form a membrane and placing the membrane onto the 20-micron PC sheet to be irradiated; after the chemical etching, uranium-bearing particles can be identified by observing the tracks to lay a foundation for the isotope ratio analysis of uranium-bearing particles with SIMS. Comparatively, the latter method is simpler.…”

In this study, an advanced method has been developed to identify uranium-bearing particles through fission track and make the particles and fission track detector form a whole. This method can result in the oneto-one correspondence between the fission track and uranium-bearing particles. It is unnecessary to separate the particles from the detector and relocate the particles when they are picked up under microscope. This simple identification is helpful in reducing the loss of particles, which would be picked up and transferred to mass spectrometer for analysis.
