The laser ablation (LA) method is an effective technique for quantitative analysis. In the present work, a new LA system was developed for the high-sensitivity analysis of metal materials using inductively coupled plasma mass spectrometry (ICP-MS). This system consists of a high-frequency Q-switched laser and 2 scanning mirrors for scanning the ablation spot in an adequately large area of the s...

Inductively coupled plasma-mass spectrometry (ICP-MS) is the method of choice for analysis of most elements across the periodic chart. Its multi-element capability, low detection limit (ppt), and wide dynamic range (109 orders of magnitude) also make it ideal for the measurement of inorganic engineered nanoparticles (ENPs). While ICP-MS can be used directly to obtain concentrations of nanoparti...

Nafion-coated bismuth film electrodes (NCBFEs) and Nafion-coated mercury film electrodes (NCMFEs) were used to electrochemically preconcentrate metal analytes for subsequent analysis by inductively coupled plasma-mass spectrometry (ICP-MS). Either type of electrodes is part of a thin-layer electrochemical flow cell that is positioned upstream of a microconcentric nebulizer for the ICP-MS. Perfo...

Through analysis of their chemical composition, human teeth may serve as retrospective bioindicators of preand postnatal nutrition and exposures to environmental pollutants. The research presented here explores the agreement of laser ablation ICP-MS and solution ICP-MS analyses aimed at capturing temporal changes in the trace element composition of enamel. Good agreement was found for LA-ICP-MS...

Abstract. Uranium–lead (U–Pb) dating of carbonates by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) spot analysis is an increasingly used method in the field geosciences, as it brings very strong constraints over geological history basins, faults or reservoirs. Most ages currently published are based on measurement U and Pb ratios ablations, using nanosecond lasers to ...

Abstract. The North Pamir, part of the western syntax India–Asia collision zone, preserves remnants a poorly understood Paleozoic intra-oceanic subduction zone. To constrain age this ancient ocean floor, we analyzed calcite phases in vesicular basalt and basaltic volcanic breccia with U–Pb geochronology using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). Dating radial...
