Trace analysis of high-purity graphite by LA–ICP–MS

Analytical and Bioanalytical Chemistry, 2001
Laser-ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) has been established as a very efficient and sensitive technique for the direct analysis of solids. In this work the capability of LA-ICP-MS was investigated for determination of trace elements in high-purity graphite.

Capability of fs-LA-ICP-MS for sulfide analysis in comparison to ns-LA-ICP-MS: reduction of laser induced matrix effects?

Journal of Analytical Atomic Spectrometry, 2015
We evaluate fractionation effects in sulfides applying ns- and fs-LA-ICP-MS and find that elemental fractionation is independent of melting.

LA-ICP-MS of magnetite: methods and reference materials

Journal of Analytical Atomic Spectrometry, 2011
Magnetite (Fe3O4) is a common accessory mineral in many geologic settings. Its variable geochemistry makes it a powerful petrogenetic indicator. Electron microprobe (EMPA) analyses are commonly used to examine major and minor element contents in magnetite.

LA-ICP-MS Analysis of Trace Elements in Yanzhuang

2020
By taking the whole-rock melt phase, silicate melt phase, and FeNi metal phase in the Yanzhuang chondrite as research objects, this paper conducted trace element measurement of each phase using the LA-ICP-MS technique. The results show that (1) during the shock-induced melting of the Yanzhuang chondrite, the siderophile elements Fe, Ni, and Co are ...

Current approaches to calibration of LA-ICP-MS analysis

Journal of Analytical Atomic Spectrometry, 2015
For solid sample quantitative analysis by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) the main analytical problems are adequate standards preparation and signals standardization.

The Role of LA-ICP-MS in the Investigation of Archaeological Glass

2016
A number of analytical techniques (e.g. SEM-EDX, XRF) are able to provide glass scientists with quantitative information on major and minor components of historical glass. However, at present, only LA-ICP-MS can deliver precise and accurate data on major, minor and trace (down to ppm or sub-ppm levels) elements with minimal or no sample preparation ...

Contributions of LA-ICP-MS to Obsidian Sourcing in the Pacific

2016
This chapter examines results from the application of LA-ICP-MS to the identification of sources of obsidian artifacts from the Western Pacific. More than 700 analyses of obsidian samples collected at the Australian National University over the past years provide an accurate geochemical dataset for major obsidian source regions in the Western Pacific ...
