“…22,[25][26][27] The use of pulsed discharge in combined hollow cathode allows sputtering of dielectric material; however, atomisation efficiency is to the great extent dependent on the formation of surface conducting layer and may vary considerably for the samples of different types. The design of the instrument and its analytical capabilities were previously discussed.…”

A direct method of uranium and thorium determination in non-conducting geological samples using timeof-flight mass spectrometry with pulsed glow discharge was proposed. The following rock specimens were analysed: metamict zircon, metamict rinkite, metamict samarskite (Y-Fe-niobate), pyrochlore and jacinth.For sample sputtering a combined hollow cathode cell of high purity aluminium or tantalum hollow cathodes was used. Powdered or monolith samples were pressed into the surface of the powdered metal prior to analysis. Model samples (artificial mixtures of oxides) were proposed for calibration; additionally, relative sensitivity factors, internal standardisation and standard additions were employed.For validation, IAEA artificially prepared uranium ore reference material was analysed. For additional validation, the obtained results for real mineral samples were compared to the results of inductively coupled plasma optical emission spectrometry after sample dissolution and semi-quantitative data of energy dispersive X-ray spectrometry. Limits of detection (3s) for the designed method were 0.3 ppm for uranium and 0.5 ppm for thorium, which is comparable to laser ablation inductively coupled plasma mass spectrometry. The method was also tested for capability to measure isotope ratios for lead and uranium without specific isotope calibration. Acquired isotopic ratios of uranium and lead corresponded to their natural abundances within the experimental error.

“…Glow discharge mass spectrometry (GDMS) is a promising technique for analyzing a variety of solids 33–35 . GDMS allows for the effective quantification of admixture elements in conducting materials and dielectrics 33,34,36,37 and it is also capable of elemental and isotopic analysis of minerals, 38–40 powders, 41 and microparticles, 42 and layer‐by‐layer analysis of thin films and coatings 43,44 .…”

Rationale: Dopants in ionic conductors play a crucial role in achieving the required electrochemical properties. A slight variation in their concentration considerably affects the conductivity of crystals and their applicability as ionic conductors and laser materials. To ensure the growth of high-quality fluoride crystals, adequate approaches for the quantification of matrix and admixture/dopant components are required. Methods: A panel of SrF 2 -and GdF 3 -doped LaF 3 single crystals was investigated.The electrical conductivity of the crystals was measured using impedance spectroscopy in the frequency range 100 Hz-1 MHz to control for crystal quality.Pulsed glow discharge mass spectrometry (GDMS) was used to simultaneously quantify fluorine, strontium, lanthanum, and gadolinium in the crystals. X-ray fluorescence, scanning electron microscopy-energy dispersive X-ray spectroscopy, and arc optical emission spectrometry were used for validation.Results: Quasiperiodic intensity drifts under sputtering of the ionic conductors were observed and attributed to F − redistribution on the sample surface, affecting surface conductivity and sputtering rate. Several sample preparation protocols were tested to address that effect. Full coating of the sample with a layer of silver several micrometers thick provided stable and effective sputtering. The parameters for the GDMS determination of F, Sr, La, and Gd were optimized. The elements' distribution was studied in different parts of the crystals. Conclusions:An analytical approach to the direct multi-element analysis of fluoridecontaining ionic conductors using pulsed GDMS with La 1−x−y Sr x Gd y F 3−x as an example was designed and tested. Instability effects of ionic conductivity were explained and coped with, providing effective and stable sputtering.
