Combination of Micro X-Ray Fluorescence Spectroscopy and Time-of-Flight Secondary Ion Mass Spectrometry Imaging for the Marker-free Detection of NM212 CeO2 Nanoparticles in Tissue Sections

01-Jun-2018 | Lothar Veith; Dörthe Dietrich; Antje Vennemann; Daniel Breitenstein; Carsten Engelhard; Uwe Karst; Michael Sper ..., Journal of Analytical Atomic Spectrometry, 2018

The description of nanoparticle distributions in tissue and associated effects is an important goal of nanotoxicology. Three-dimensional time-of-flight-secondary ion mass spectrometry (3D ToF-SIMS) is a promising label-free method to analyse tissue sections for nanoparticle distribution and to ...

Matrix dependency of baddeleyite U–Pb geochronology by femtosecond-LA-ICP-MS and comparison with nanosecond-LA-ICP-MS

01-Jun-2018 | Cora C. Wohlgemuth-Ueberwasser; Jan A. Schuessler; Friedhelm von Blanckenburg; Andreas Möller, Journal of Analytical Atomic Spectrometry, 2018

Baddeleyite is a key mineral in geochronology of mafic rocks as it crystallizes in silica-undersaturated systems that do not grow zircon. It has been shown that nanosecond (ns-)LA-ICP-MS U–Pb analysis requires matrix-matched calibration due to significantly stronger element downhole fractionation ...

Multi-element analysis of single nanoparticles by ICP-MS using quadrupole and time-of-flight technologies

31-May-2018 | Steffi Naasz; Stefan Weigel; Olga Borovinskaya; Andrius Serva; Claudia Cascio; Anna K. Undas; Felice C. Simeone; Han ..., Journal of Analytical Atomic Spectrometry, 2018

Determining composition, shape, and size of nanoparticles dispersed in a complex matrix is necessary in the assessment of toxicity, for regulatory actions, and environmental monitoring. Many types of nanoparticles that are currently used in consumer products contain more than one metal which are ...

Determination of yttrium in titanium alloys using laser-induced breakdown spectroscopy assisted with laser-induced fluorescence

30-May-2018 | M. Shen; C. M. Li; D. Na; Z. Q. Hao; X. Y. Li; L. B. Guo; Y. F. Lu; X. Y. Zeng, Journal of Analytical Atomic Spectrometry, 2018

Determining the concentration of material enhancing elements is one of the key issues for ensuring the quality and performance of titanium alloy products. Traditional methods used for determining these elements lack the ability of fast and in situ analysis, and have slowed the research and ...

Naturally occurring molecular species used for plasma diagnostics and signal correction in microwave-induced plasma optical emission spectrometry

30-May-2018 | Charles B. Williams; Bradley T Jones; George L. Donati, Journal of Analytical Atomic Spectrometry, 2018

In the present study, we evaluate the N2+ / OH emission intensity ratio as a diagnostic tool for identifying the best instrumental operating conditions in microwave-induced plasma optical emission spectrometry (MIP OES). This molecular species signal ratio is compared with the traditional Mg II / ...

Usefulness of ionic liquids as mobile phase modifiers in HPLC-CV-AFS for mercury speciation analysis in food

30-May-2018 | Alexander Castro Grijalba; Pamela Y. Quintas; Emiliano F. Fiorentini; Rodolfo G. Wuilloud, Journal of Analytical Atomic Spectrometry, 2018

Different ionic liquids (ILs) were studied in this work as mobile phase modifiers for the separation and determination of Hg2+, methylmercury (CH3Hg+) and ethylmercury (C2H5Hg+) species by reversed-phase high-performance liquid chromatography coupled to UV-cold vapor atomic fluorescence ...

Quantitative elemental analysis of polymers through laser ablation – inductively coupled plasma by using a dried droplet calibration approach, DDCA

30-May-2018 | Ángela Villaseñor; Marina Boccongelli; José Luis Todolí, Journal of Analytical Atomic Spectrometry, 2018

The so-called Dried Droplet Calibration Approach (DDCA) was applied for the first time to the determination of elemental concentration in polyethylene and polypropylene samples by means of inductively coupled plasma optical emission spectrometry (ICP-OES) and mass spectrometry (ICP-MS). Based on ...
