Themed collection Community Leaders: Ramon Barnes

Guest Editors Gary M. Hieftje and Joanna Szpunar introduce this themed collection in honor of Ramon M. Barnes.

We present a new data acquisition unit with nanosecond time resolution (nanoDAQ) for single particle inductively coupled plasma mass spectrometry (spICP-MS), which is able to detect gold nanoparticles below 10 nm with a single quadrupole ICP-MS.

A systematic approach towards high resolution quantitative multi-element imaging of biological tissue by ICP-TOFMS.

The analysis of large nanomaterials with only one dimension in the range of nanometers (nanoclays) by SP-ICP-MS is proposed.

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.

Emission intensity of oxygen at 777 nm in Cu-, Al-, Mg- and Fe-matrices.

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.

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.

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.

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).

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.

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.

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.

Compressed sensing improves sample throughput by orders of magnitude of GDOES elemental mapping via single-pixel spectral imaging.

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.

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 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.

A microwave-assisted extraction (MAE) method for further Cl, Br, and I determination in medicinal plants was developed.

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.

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.

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.

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.

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.
