Percolation Diffusion into Self-Assembled Mesoporous Silica Microfibres [PDF]
Nanomaterials, 2014 Percolation diffusion into long (11.5 cm) self-assembled, ordered mesoporous microfibres is studied using optical transmission and laser ablation inductive coupled mass spectrometry (LA-ICP-MS).

Direct Calibration Method for LA-HR-ICP-MS Apatite U-Pb Dating
Yankuang ceshi, 2022 BACKGROUND Apatite is a common U-bearing accessory mineral with a U-Pb closure temperature of ~500℃, making U-Pb dating of apatite a potentially valuable thermochronometer.

Study on the Morphology of Zircon-bearing Epoxy Resin Surface and Its Effect for LA-ICP-MS Analysis
Yankuang ceshi, 2020 BACKGROUND Laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) is currently one of the commonly used methods for zircon research. This method generally uses epoxy resin targets as carriers.

LA‐ICP‐MS/MS Single‐Spot Rb‐Sr Dating [PDF]
Geostandards and Geoanalytical Research, 2022 Due to developments in reaction cell technologies, it is now possible to collect large 87Rb/86Sr and 87Sr/86Sr data sets using LA‐ICP‐MS/MS. Until now, LA‐ICP‐MS/MS Rb‐Sr ages were constrained using conventional isochrons on a contiguous set of Rb‐Sr data.

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

What does the impurity variability at the microscale represent in ice cores? Insights from a conceptual approach [PDF]
The CryosphereMeasuring aerosol-related impurities in ice cores gives insight into Earth's past climate conditions. In order to resolve highly thinned layers and to investigate post-depositional processes, such measurements require high-resolution analysis, especially
