Simultaneous determination of trace elements in minute samples by electrothermal-vaporization/low-pressure helium-ICP-MS.
Electrothermal vaporization with two filaments was studied for low-pressure helium-ICP-MS. A 10-microl volume of sample was dried and vaporized, and then introduced to the ICP. With this technique, four elements were simultaneously determined with the acceptable precisions (RSD ca. 10%). The detection limit based on 3sigma of background signals approached the fractional ppb range. The proposed ...
متن کاملDetermination of trace elements in filtered suspended marine particulate material by sector field HR-ICP-MS
Quantification of particulate (w0.45 mm) and dissolved (v0.45 mm) trace elements in seawater is imperative for understanding geochemical cycling in the marine environment. Suspended particulate trace element concentrations are typically v10% of total element concentrations in seawater. To overcome analytical difficulties associated with low analyte concentrations, it is common to filter large v...
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 کاملDetermination of trace elements in marine plankton by inductively coupled plasma mass spectrometry (ICP-MS).
A method has been developed for the determination of 23 elements in marine plankton in which inductively coupled plasma (ICP) source mass spectrometry (MS) was used to quantify the elements in the solution after digestion in a mixture of hydrofluoric and nitric acids in sealed PTFE vessels in a microwave field. The procedure was validated by the analysis of a standard reference soil (SRM 2709 S...
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...
