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.

Agrometallomics, as an independent interdiscipline, is first defined and described in this review. Metallic elements widely exist in agricultural plants, animals and edible fungi, seed, fertilizer, pesticide, feedstuff, as well as the agricultural environment and ecology, and even functional and pathogenic microorganisms. So, the agrometallome plays a vital role in molecular and organismic mechanisms like environmetallomics, metabolomics, proteomics, lipidomics, glycomics, immunomics, genomics, etc. To further reveal the inner and mutual mechanism of the agrometallome, comprehensive and systematic methodologies for the analysis of beneficial and toxic metals are indispensable to investigate elemental existence, concentration, distribution, speciation, and forms in agricultural lives and media. Based on agrometallomics, this review summarizes and discusses the advanced technical progress and future perspectives of metallic analytical approaches, which are categorized into ultrasensitive and high-throughput analysis, elemental speciation and state analysis, and spatial- and microanalysis. Furthermore, the progress of agrometallomic innovativeness greatly depends on the innovative development of modern metallic analysis approaches including, but not limited to, high sensitivity, elemental coverage, and anti-interference; high-resolution isotopic analysis; solid sampling and nondestructive analysis; metal chemical species and metal forms, associated molecular clusters, and macromolecular complexes analysis; and metal-related particles or metal within the microsize and even single cell or subcellular analysis.

“…The most widely adopted method in previous studies is to compact the soil with high purity metal (such as aluminium, silver, copper and tantalum and so on) as a conductive binder to form a pin or plate-shaped cathode. [16][17][18]21 However, the soils are hard to be mixed with conductive binder uniformly to form pin or plate-shaped cathodes with a certain mechanical strength, the process of which is often time-consuming and easy to bring in secondary contamination. The second approach is to cover a metallic secondary cathode diaphragm at the surface of the soil plate, allowing the surface covered by a thin metallic layer during sputtering.…”

Atomic spectrometry (AES/AAS), 8 inductively coupled plasma mass spectrometry (ICP-MS), [9][10][11] instrumental neutron activation analysis (INNA), 12,13 X-Ray fluorescence spectrometry (XRF), 14 laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) 15 and glow discharge mass spectrometry (GD-MS) [16][17][18][19][20][21][22] has been used in geology and geochemistry surveys. However, due to the refractory nature of the soil samples, the sample preparation is time-consuming with the risk of sample contamination from chemical reagents in dissolve process when utilizing the conventional solutionbased approaches, such as ICP.…”
