Statoliths of the gonatid squid Gonatus fabricii from Disko Bay, West Greenland, were analysed by laser ablation inductively coupled plasma mass-spectrometry (LA-ICP-MS) to determine the concentrations and spatial distributions of 9 minor and trace elements (Sr, Ba, Mg, U, Zn, Mn, Y, Zr, Na). Element composition was assigned in situ to distinct statolith regions, corresponding to ontogenetic st...

Abstract. The ability to constrain the age of calcite formation is great utility Earth science community, due ubiquity across a wide spectrum geological systems. Here, we present first in situ laser ablation inductively coupled tandem quadrupole mass spectrometry (LA-ICP-MS/MS) Lu–Hf ages for calcite, demonstrating geologically meaningful iron oxide copper gold (IOCG) and skarn mineralisation, ...

An insight into the effect of species-specific calibration on accuracy LA-ICP-MS data for tissue Fe and Se at concentrations relevant to neurodegenerative models.

A home-made system hyphenating capillary electrophoresis with an inductively coupled plasma mass spectrometer (CE-ICP-MS) for cadmium speciation of protein-binding and free cadmium ions in solution is presented. The CE-ICP-MS interface consisted of an acrylic block with an internal volume ca. 20 microL in which a platinum electrode, a capillary column, and a connection to an ICP nebulizer were ...

Wetland snakes, as top predators, are becoming globally recognised bioindicators of wetland contamination. Livers the traditional test organ for contaminant exposure in organisms, but research is moving towards a preference non-lethal tissue sampling. Snake scales can be used an indicator exposure, many metals bind to keratin. We laser ablation with inductively coupled plasma-atomic emission sp...

This paper is a performance evaluation of a prototype laser-ablation microanalytical system composed of an UV Excimer laser and a high-sensitivity inductively coupled plasma mass spectrometer (XLA-ICP-MS). The laser was optimized for trace-element microanalysis of silicate minerals, and the effects of different parameters (laser power, focus, carder gas flow, etc.) on the performance characteri...

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...

Laser ablation with inductively coupled plasma-mass spectrometry (LA-ICP-MS) was used to measure elemental concentrations at the 100-μm scale in a 3-dimensional manner within a basaltic clast sample collected from the Hanford 300 Area in south-central Washington State, United States. A calibration method was developed to quantify the LA-ICP-MS signal response using a constant-sum mass fraction ...
