A unified approach to mechanistic aspects of photochemical vapor generation
A general model of redox reactions for PVG is proposed, driven by reducing radicals (e(aq)−, H˙, R˙ and CO2˙−) arising from concurrent VUV photolysis of carboxylic acids to yield the nascent elemental species which are subsequently attacked by H˙, H3C˙, H+ and CO to yield volatile products.
Quantification of non-transferrin bound iron (NTBI) in human serum by isotope dilution mass spectrometry (IDMS)
NTA·57Fe is used to capture NTBI and saturate transferrin with iron so that NTBI can be separated through ultrafiltration.
Paper
A quantitative nanoparticle extraction method for microsecond time resolved single-particle ICP-MS data in the presence of a high background
A new method for the quantification of dissolved ions and nanoparticles in mixtures with SP-ICP-MS with microsecond time resolution.
Investigations of matrix independent calibration approaches in fast flow glow discharge mass spectrometry
The performance of glow discharge mass spectrometry (GD-MS) is investigated for the accurate quantification of metallic impurities and oxygen in solid samples using the fast flow source GD-MS instrument ELEMENT GD.
Quantitative speciation analysis for the in vivo study of iron metabolism and bioavailability from formula milk fortified with stable isotope enriched iron oxo-hydroxide nanoparticles
For the first time, the study of iron metabolism and bioavailability, administered as stable iron isotope enriched nanoparticles, was carried out by speciation analysis.
Ultra-trace element analysis of human follicular fluid by ICP-MS/MS: pre-analytical challenges, contamination control, and matrix effects
Human follicular fluid was collected from 56 women undergoing IVF treatment and analyzed for 11 (ultra-)trace elements using a “dilute and shoot” ICP-MS/MS method.
High speed-low volume automated ICP-QMS method for determination of Mg/Ca in biogenic calcite
The Mg/Ca molar ratio in foraminiferal calcite accumulated in marine sea sediments is a well-established proxy of ancient ocean temperatures.
Measurement of compound-specific Hg isotopic composition in narrow transient signals by gas chromatography coupled to multicollector ICP-MS
Hg species-specific delta values are obtained from isotope ratios measured in short transient signals by GC-MC-ICP-MS.
Accurate quantification of carboplatin adducts with serum proteins by monolithic chromatography coupled to ICPMS with isotope dilution analysis
This work demonstrates for the first time the potential of monolithic chromatography coupled to double species-specific isotope dilution analysis (IDA) inductively coupled plasma mass spectrometry (ICPMS) for the detection and accurate quantification of adducts of plasma/serum proteins with carboplatin, an anti-cancer drug.
LA-ICP-TOF-MS for rapid, all-elemental and quantitative bioimaging, isotopic analysis and the investigation of plasma processes
This work presents a high-throughput and quasisimultaneous, full-spectral imaging approach for the analysis of cisplatin perfused rat kidneys using LA-ICP-TOF-MS.
Paper
Single-particle ICP-MS with online microdroplet calibration: toward matrix independent nanoparticle sizing
Microdroplets with known concentrations of element standards are introduced concomitant with NP-containing solutions into the ICP to provide online matrix-matched calibration of analyte NPs for single-particle-ICP-TOFMS.
Development of a method for the quantitative metabolite profiling of pharmaceutical drugs using HPLC-ICP-MS following pre-column derivatization of their amino and hydroxyl groups using 4-aminopyridine as a model compound
Presence of amino and/or hydroxyl groups allows for derivatization of APIs and their metabolites with 4-iodobenzoylchloride, thus enabling HPLC-ICP-MS metabolite profiling.
Elucidation of the fate of zinc in model plants using single particle ICP-MS and ESI tandem MS
The fate of zinc in model plants was studied by an analytical approach based on mass spectrometry techniques.
Plasma profiling-time of flight mass spectrometry: considerations to exploit its analytical performance for materials characterization
The combination of pulsed glow discharge (PGD) with time-of-flight mass spectrometry (TOFMS) provides quasi-simultaneous mass spectra of fast transient signals directly from solid materials.
Determination of trace elements in undiluted wine samples using an automatized total sample consumption system coupled to ICP-MS
A novel method for the elemental analysis of undiluted wine samples was optimized and validated.
Direct elemental analysis of petroleum heavy fractions by means of ICP-OES equipped with a high temperature torch integrated sample introduction system
The present work describes and discusses the use of a high temperature sample introduction system, hTISIS, for the analysis of crude oil and heavy petroleum fractions by means of inductively coupled plasma optical emission spectrometry, ICP-OES.
Critical evaluation of fast and highly resolved elemental distribution in single cells using LA-ICP-SFMS
The analytical potential of a nanosecond laser ablation inductively coupled plasma mass spectrometer system, equipped with an ultra-fast wash-out ablation chamber, is critically investigated for fast and highly spatially resolved (∼μm) qualitative elemental distribution within single cells.
