Exploring the boundaries in the analysis of large particles by single particle inductively coupled plasma mass spectrometry: application to nanoclays
The analysis of large nanomaterials with only one dimension in the range of nanometers (nanoclays) by SP-ICP-MS is proposed.
Size determination of nanoparticles by ICP-ToF-MS using isotope dilution in microdroplets
Combination of microdroplet generator and ICP-ToF-MS for nanoparticle sizing via on-line ID (on-line ID-MDG-sp-ICP-ToF-MS). 194Pt/195Pt ratio was used for sizing of the particles, while 182W/183W ratio used simultaneously for mass bias correction.
Investigation of matrix independent calibration of oxygen in glow discharge optical emission spectrometry
Emission intensity of oxygen at 777 nm in Cu-, Al-, Mg- and Fe-matrices.
A novel solution cathode glow discharge geometry for improved coupling to optical emission spectrometry
The Solution-Cathode Glow-Discharge (SCGD) is an atmospheric pressure glow discharge used for atomic emission spectrometry that is sustained between a metallic pin-anode and a liquid cathode, which is also the sample solution.
Method development for speciation analysis of silver nanoparticles and silver ions in green algae and surface waters at environmentally relevant concentrations using single particle ICP-MS
Interactions of Ag+ and AgNPs of different nominal diameters (40, 60 and 75 nm) with green microalgae Desmodesmus subspicatus during a 24 h incubation period in matrices that mimic surface water and natural river water were studied by single particle ICP-MS.
Mass spectrometry insights into interactions of selenoprotein P with auranofin and cisplatin
The reactivity of selenoprotein P (a serum selenoprotein containing 10 selenocysteine (SeCys), 17 cysteine (Cys) and 14 histidine (His) residues) with two metallodrugs (auranofin and cisplatin) was investigated.
Critical evaluation of SCGD-OES analytical performance in the presence of NaCl
The present study deals with the influence of sodium chloride (NaCl) on the analytical response and performance of solution-cathode glow discharge coupled to optical emission spectroscopy (SCGD-OES).
Quantitative elemental bioimaging: an antibody-based double-labelling method to quantify the cell-specific distribution of silver nanoparticles in lung tissue sections
The LA-ICP-MS image shows an overlay of the m/z 197 signal of colloidal gold labelled macrophages (green) and the m/z 107 signal of silver nanoparticles (red) in lung tissue, with colocations of Au and Ag in yellow colour.
Improved uranium isotopic ratio determinations for the liquid sampling-atmospheric pressure glow discharge orbitrap mass spectrometer by use of moving average processing
Applying moving average processing to isotope ratio determinations collected using an LS-APGD source coupled with an Orbitrap MS increases the precision of the measurements and reduces the number of points needed to collect high precision data.
Use of single particle inductively coupled plasma mass spectrometry for the study of zinc oxide nanoparticles released from fabric face masks
An analytical method based on single particle inductively coupled plasma mass spectrometry (SP-ICP-MS) was developed to study the release of ZnO nanoparticles from fabric face mask samples upon washing.
High-throughput single pixel spectral imaging system for glow discharge optical emission spectrometry elemental mapping enabled by compressed sensing
Compressed sensing improves sample throughput by orders of magnitude of GDOES elemental mapping via single-pixel spectral imaging.
Laser ablation-ICP-mass spectrometry for determination of the concentrations and spatial distributions of bromine and iodine in human hair
Laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) was applied for the determination of Br and I in hair strands of human individuals under treatment with synthetic thyroid hormones.
Direct analysis of tree rings using laser ablation-ICP-MS and quantitative evaluation of Zn and Cu using filter paper as a solid support for calibration
This work aims to study and apply filter paper as calibration solid supports, in order to avoid matrix and fractionation effects, for the quantification of two essential elements of trees, Cu and Zn, in tree-ring samples, using LA-ICP-MS.
GC-MS exploration of photochemically generated species of Os, W and Ru from reductive and oxidative media
GC-MS identification of W(CO)6 and OsO4 confirms these products of photochemical vapor generation from W(VI) and Os(IV) in reductive and oxidative media, respectively.
Microwave-assisted extraction for further Cl, Br, and I determination in medicinal plants by ICP-MS: a study of carbon interferences
A microwave-assisted extraction (MAE) method for further Cl, Br, and I determination in medicinal plants was developed.
The sensitive determination of Ag, Pb and Tl as well as reduction of spectral interferences in a hanging drop cathode atmospheric pressure glow discharge excitation microsource equipped with a Dove prism system
A hanging drop cathode APGD-OES system coupled with Dove prism is reported. The reduction of spectral interferences and enhancement of the Ag, Pb and Tl atomic emission lines was the most spectacular and resulted in improved LODs of these elements.
Strontium isotopic analysis of environmental microsamples by inductively coupled plasma – tandem mass spectrometry
A method for direct (without chromatographic Rb/Sr separation) Sr isotopic analysis using tandem ICP-MS has been optimized for small-size environmental samples and applied to Antarctic PM10 and soil samples from South America and Australia as proof-of-concept.
Optimization of a CE-ICP-MS/MS method for the investigation of liposome–cisplatin nanosystems and their interactions with transferrin
This study aims to elaborate on a novel comprehensive CE-ICP-MS/MS method for liposome-based cisplatin delivery system characterization. The optimized method allows for direct monitoring of formation products, the drug loading efficiency, and the stability of systems under proteinaceous conditions.
Ilaps – python software for data reduction and imaging with LA-ICP-MS
In the past couple of years, laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) has been widely used for trace element analysis in solid samples and the study of their distribution.
Comparison of monosegmented flow analysis to flow injection for single particle inductively coupled plasma mass spectrometry
Monosegmented flow analysis doubles the sample throughput of flow injection, and provides accurate nanoparticle mass without measuring the transport efficiency.

No changes of arsenic speciation after sampling and fast ICP MS determination.
