Online preconcentration ICP-MS analysis of rare earth elements in seawater
[1] The rare earth elements (REEs) with their systematically varying properties are powerful tracers of continental inputs, particle scavenging intensity and the oxidation state of seawater. However, their generally low ( pmol/kg) concentrations in seawater and fractionation potential during chemical treatment makes them difficult to measure. Here we report a technique using an automated precon...
متن کاملAnalysis of Trace Elements in Teeth by ICP-MS: Implications for Caries
Teeth are good indicators of environmental exposure to heavy metals and of nutritional status. Inductively coupled plasma-mass spectrometry (ICP-MS) was used to compare the content of trace elements in primary and permanent teeth. For this purpose, primary teeth were collected from 64 children and 112 permanent teeth were collected from 40to 60-year-old adults. The data were assessed statistica...
متن کاملDirect measurement of trace rare earth elements (REEs) in high-purity REE oxide using the Agilent 8800 Triple Quadrupole ICP-MS with MS/MS mode
Rare earth elements (REE) are widely used in advanced technology. Praseodymium (Pr), neodymium (Nd), samarium (Sm) and dysprosium (Dy) are used in high-power permanent magnets. Ytterbium (Yb), erbium (Er) and holmium (Ho) are used in lasers. Lanthanum (La), gadolinium (Gd), terbium (Tb), europium (Eu) and Yb are components of luminescent and fluorescent phosphors, used in fluorescent lamps, rad...
متن کاملInfluence of digestion procedures on the determination of rare earth elements in peat and plant samples by USN-ICP-MS
Analytical procedures for the determination of rare earth elements (REE) in 250 mg aliquots of difficult-todigest peat and plant matrices by ICP-MS were developed. Three different pressurised digestion approaches were tested for this purpose, namely (i) closed vessel acid digestion on a hot-plate at 180 uC, (ii) digestion in a microwave high pressure autoclave at a temperature of 240 uC and (ii...
متن کاملLA-ICP-MS analysis of trace elements in biogenic minerals: time series recording of environmental changes
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...
