Seven ilmenite (FeTiO3) megacrysts derived from alnöite pipes (Island of Malaita, Solomon Islands) were characterised for their major and trace element compositions in relation to their potential use as secondary reference materials for in situ microanalysis. Abundances of thirteen trace elements obtained by laser ablation ICP-MS analyses (using the NIST SRM 610 glass reference material) were c...

In the present study. the metal-containing proteins in the roots ofCu-tole rant plant ElsllOltzia splendens were investigated. The proteins from the plant roots were extracted and separated by two-dimensional gel electrophoresis (2D GE). Las er ablation inductively coupl ed plasma mass spectrometry (LA-ICP-MS) was used to screen metal-containing proteins on the dried 2D gels. Images of Cu. Zn. ...

New analytical techniques for multiparametric characterisation of individual cells are likely to reveal important information about the heterogeneity of immunological responses at the single-cell level. In this proof-of-principle study, laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) was applied to the problem of concurrently detecting 24 lineage and activation markers e...

The aim of the study is to better understand where uranium deposits in mice kidneys. The spatial distribution of uranium was examined in the kidneys of C57BL/6 mice using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). Mice were exposed to varying levels of uranyl nitrate in their drinking water. Calibration standards were developed to allow for semi-quantitative measur...

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). Optical transmission based diffusion studies reveal rapid penetration (<5 s, D > 80 μm²∙s-¹) of Rhodamine B with very little percolation of larger molecules such as zinc tetraphenylporphyrin (ZnTPP) obs...

Nickel alloys are used extensively across a wide range of industries, often in components which are required to perform critical functions under arduous operating conditions. As a result, the physical, chemical, and mechanical properties of such alloys must be well understood and the levels of trace metal contaminants, which may have a profound effect on these properties, must be strictly contr...

Laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) was used to determine the Pb/Ca ratios in the enamel of deciduous incisors, a biomarker of in utero Pb exposure, using pelletized bone certified reference materials (CRMs) as calibrants. The detection limit for Pb by LA-ICP-MS was 11 microg kg(-1) demonstrating an adequate sensitivity for Pb in the teeth of unexposed indivi...

• Multi-Element Analysis Introduction Laser ablation inductively coupled plasma-mass spectrometry (LA-ICP-MS) has developed over recent years to become a sophisticated tool for the multielemental and isotope ratio analysis of solid samples. Besides a true multi-elemental capability, independent of matrix, the major requirements for most geological laser applications in ICP-MS are the highest se...

Laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) is a widely accepted method for direct sampling of solid materials for trace elemental analysis. The number of reported applications is high and the application range is broad; besides geochemistry, LA-ICP-MS is mostly used in environmental chemistry and the life sciences. This review focuses on the application of LA-ICP-MS...
