Evaluating U-Pb accuracy and precision by comparing zircon ages from 12 standards using TIMS and LA-ICP-MS methods

Geosystems and Geoenvironment, 2023
U-Pb geochronological studies based on LA-ICP-MS isotopic measurements often require a profound understanding of the accuracy, precision, and preferred ages derived from this methodology.

NANOPARTICLES AS A BIORECOGNITION PLATFORM IN COMBINATION WITH LA-ICP-MS [PDF]

NANOCON Conference Proeedings, 2020
Metal nanoparticles proved to be effective signaling tags in combination with laser ablation followed by inductively coupled plasma mass spectrometric detection. The surface may be suitably modified by various biorecognition elements such as antibodies or aptamers. Moreover, molecularly imprinted polymers can be prepared on their surface. In this study,

In-situ Non-destructive Determination of Major and Trace Elements in Large Size Ceramic Samples by Open Laser Ablation Inductively Coupled Plasma-Mass Spectrometry

Yankuang ceshi, 2021
BACKGROUND Usually, laser ablation inductively coupled plasma-mass spectrometry (LA-ICP-MS) analysis is equipped with a closed ablation cell. It cannot be used for non-destructive analysis of the large-size samples which exceeds the size of the cell ...

What does the impurity variability at the microscale represent in ice cores? Insights from a conceptual approach [PDF]

The Cryosphere
Measuring 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
