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.

Microanalysis of ceramics with PIXE and LA-ICP-MS

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2002
Abstract The provenance postulate states that artifact raw material sources can be determined by chemical characterization as long as between-source chemical differences exceed within-source variation. For ceramics, successful differentiation of sources usually requires the measurement of a large suite of elements.

The Role of LA–ICP–MS in Palaeoclimate Research

Elements, 2016
Past environmental parameters such as temperature, pH and CO2 can be reconstructed from chemical 'proxies' (elemental and isotopic compositions) stored in various 'archives' such as corals, foraminifera and bivalves. Versatile, rapid, simple and comparatively inexpensive microanalysis via laser ablation inductively coupled plasma mass spectrometry (LA ...

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.

Analytical Dating in Geological Science (LA-ICP-MS)

Proceedings, 2011
The project samples are metasediments from the south of Spain, spanning late Proterozoic to Ordovician in age. The question being addressed is whether the provenance of zircons in these samples changed during this interval. There is evidence using Nd and O isotopes that there is a big shift in the middle of the sequence that reflects the availability ...

Precious Metals and Provenance Enquiries using LA-ICP-MS

Journal of Archaeological Science, 1999
While the manufacture technology of archaeological gold and silver objects can often be explained by using classical analytical techniques, the origin of these precious metals remains difficult to determine. In most cases, several trace elements and/or lead isotope ratios must be measured in order to find the object to mine.
