The use of oxygen as a reaction gas for the removal of interferences in quadrupole ICP-MS is well established. However, prior to the development of the Agilent 8800 Triple Quadrupole ICP-MS (ICP-QQQ), the use of oxygen had been limited to determination of a small number of analytes in simple, well defined matrices. This is because oxygen can react with matrix components, analytes and polyatomic...

Abstract A reliable and accurate laser ablation multi-collector inductively coupled plasma mass spectrometry (LA-MC-ICP-MS) method was developed for analysis of inhomogeneous samples containing uranium particles or aggregates various enrichments. For the development, a mixed solid standard prepared using 1% 3% 235 U enriched certified reference materials. After screening localization interest, ...

A combined method of laser ablation (LA) and ICP-MS has gained much attention as a direct analytical method for solid samples. The determination of some elements, however, is seriously disturbed by isobaric interferences, mainly caused by argon and ambient air constituents. The use of low-pressure helium-ICP is a promising solution of the problem. A 1:1 mixture of alumina powder and glycerol wa...

We present a new strategy on how to synthesize trace-element bearing (REE, Sr) chlorapatites Ca5(PO4)3Cl using the flux growth method. Synthetic apatites were up to several mm long, light blue in colour. The apatites were characterized using XRD, electron microprobe and laser ablation ICP-MS (LA-ICPMS) techniques and contained several hundred μg/g La, Ce, Pr, Sm, Gd and Lu and about 1700 μg/g S...

The potential use of Sr/Ca and Ba/Ca ratios in fish otolith, as a complement to 87Sr/86Sr study movements Prochilodus lineatus, was evaluated the La Plata Basin (South America). Water were obtained from samples collected during high low water seasons at 42 sites across Basin. Elemental isotopic measured by MC-ICP-MS, ICP-MS ion chromatography, available literature. Fish caught six different wit...

Inorganic mass spectrometric methods are widely used for the multielemental determination of elements at the trace and ultratrace level in high-purity materials (e.g., conducting, semiconducting and nonconducting solid samples, high-purity water, organic solutions and solvents). Inductively coupled plasma mass spectrometry (ICP-MS), laser ablation inductively coupled plasma mass spectrometry (L...

The objectives of the project were to improve our understanding of trace element behaviour in biogenic minerals via Laser Ablation Inductively Coupled Plasma Mass Spectrometer (LA-ICP-MS) analysis. Indeed, it is well known that biogenic carbonates continuously record environmental conditions such as temperature, salinity and also pollutant level and thus represent potential archives of environm...
