Trace elements determination in seawater by ICP-MS with on-line pre-concentration on a Chelex-100 column using a ‘standard’ instrument setup.
Trace element determination in seawater is analytically challenging due to the typically very low concentrations of the trace elements and the potential interference of the salt matrix. A common way to address the challenge is to pre-concentrate the trace elements on a chelating resin, then rinse the matrix elements from the resin and subsequently elute and detect the trace elements using induc...

متن کاملDetermination of Trace Elements in High Purity Tungsten by Solid-Phase Extraction/ICP-MS
To establish a rapid trace-quantification scheme for elements contained in highly purified tungsten, we studied the most suitable conditions for separating the elements using solid-phase-extraction as a pretreatment for inductively coupled plasma-mass spectrometry (ICP-MS). We used chemically bonded silica gels belonging to the functional group of benzylsulfonic acid as extracting agent. Tungst...
متن کاملDetermination of Trace Elements in High-Purity Molybdenum by Solid-Phase Extraction/ICP-MS
We attempted a simple pretreating method consisting of solid-phase extraction using bonded silica gel with benzenesulfonic acid (SCX) as the solid-phase sorbent to determine trace elements in pure molybdenum samples by means of inductively coupled plasma mass spectrometry (ICP-MS). Molybdenum was anionized by adding hydrogen peroxide solution to a sample decomposed with acid, and separated from...
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...
