Quantitative Determination of the Surface Distribution of Supported Metal Nanoparticles: A Laser Ablation–ICP–MS Based Approach

open access: yesChemosensors, 2021
A laser ablation–inductively coupled plasma–mass spectrometry (LA–ICP–MS) based method is proposed for the quantitative determination of the spatial distribution of metal nanoparticles (NPs) supported on planar substrates.

Two-dimensional impurity imaging in deep Antarctic ice cores: snapshots of three climatic periods and implications for high-resolution signal interpretation [PDF]

open access: yesThe Cryosphere, 2021
Due to its micrometer-scale resolution and inherently micro-destructive nature, laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) is particularly suited to exploring the thin and closely spaced layers in the oldest sections of polar

Application of LA–ICP–MS in polar ice core studies [PDF]

open access: yesAnalytical and Bioanalytical Chemistry, 2003
The direct determination of element signatures in polar ice core samples from Greenland by laser ablation with subsequent inductively coupled plasma mass spectrometry analysis has been investigated. A cryogenic sample chamber enables the element determination in ice directly from the solid (frozen) state.

Quantitative MRI and laser ablation-inductively coupled plasma-mass spectrometry imaging of iron in the frontal cortex of healthy controls and Alzheimer’s disease patients

open access: yesNeuroImage, 2020
Accumulation of iron within the cortex of Alzheimer’s disease (AD) patients has been reported by numerous MRI studies using iron-sensitive methods. Validation of iron-sensitive MRI is important for the interpretation of in vivo findings.

Whole-rock trace element analyses via LA-ICP-MS in glasses produced by sodium borate flux fusion

open access: yesBrazilian Journal of Geology, 2021
Trace elements provide crucial information about the origin and evolution of the Earth. One common issue regarding their analyses is the reduced analyte recovery during hot plate acid digestion for some geological samples. To overcome this, alkali fluxes

U‐Pb dating of zircon by LA‐ICP‐MS [PDF]

open access: yesGeochemistry, Geophysics, Geosystems, 2006
In this study we used LA‐ICP‐MS (laser ablation–inductively coupled plasma–mass spectrometry) to determine U‐Pb ages of 5 zircon samples of known age (∼1800 Ma to ∼50 Ma) in order to determine the reproducibility, precision, and accuracy of this geochronologic technique.
