On the applicability and performance of the single particle ICP-MS nano-dispersion characterization method in cases complicated by spectral interferences

Abstract

The spectral interference effects occurring in SP-ICP-MS are discussedviathe examples of the measurement of Fe2O3, Cr2O3, and ZnO particles.

Porosity determination of nano- and sub-micron particles by single particle inductively coupled plasma mass spectrometry

“…In case of compact, single component, spherical NPs, the measured intensity is in a cubic relation with the particle diameter. Through the evaluation of the signal histograms, the technique can provide information about the presence, size distribution, number concentration, elemental or isotopic composition of nanoparticles [21][22][23][24]. In our previous studies, we demonstrated that not only single component or homogenous (random) alloy spherical NPs can be analyzed, and additional information, such as the structure and aspect ratio, can also be obtained by the spICP-MS method [25,26].…”

“…Kálomista et al [24] and later Bolea-Fernandez et al [28] showed that the collision/reaction cell technology can be used advantageously in spICP-MS measurements as well for diminishing spectral interferences without sacrificing much of the size detection limits or precision of the obtained data.…”

Titán-dioxid-nanopálcikák tüdőre kifejtett hatásának állatkísérletes vizsgálata szubakut patkánymodellben

“…Az elemi Ti tüdőmintákban lévő teljes koncentrációjának meghatározása a SZTE Szervetlen és Analitikai Kémiai Tanszékén történt, induktív csatolású plazma-tömegspektrometria (ICP-MS, kvantitatív elemanalitikai módszer) alkalmazásával, savas (HNO 3 + HCl) roncsolást követően [24,25]. A biokémiai vizsgálatok elsősorban az alsó légúti alveolaris régió celluláris (alveolaris epithel, macrophag) szintű károsodásainak (akut/krónikus gyulladás, sejtpusztulás) detektálására fókuszáltak.…”

Determination of the platinum concentration of a Pt/silica nanocomposite decorated with ultra small Pt nanoparticles using single particle inductively coupled plasma mass spectrometry

“…Data evaluation in spICP-MS was performed on the histograms (frequencycount diagrams) produced from the time-resolved signal traces, as described in ref. 15. Data processing was performed using Agilent MassHunter (Santa Clara, California, USA) and OriginLab Origin (Northampton, Massachusetts, USA) soware.…”

“…Single particle, or particle-mode, ICP-MS (spICP-MS) is a novel nanoparticle (NP) characterization technique, which is recently gaining increasing attention in the literature owing to its versatility and high throughput. [12][13][14][15] In this technique, sensitive ICP-MS spectrometers are used in the time-resolved mode for the measurement of dilute nanodispersions (particle concentrations less than 10 5 mL À1 are adequate). The nanoparticles get atomized and ionized in the plasma.…”
