Determination of uranium in tap water by ICP-MS
Fresenius' Journal of Analytical Chemistry, 2000A fast and accurate procedure has been developed for the determination of uranium at microg L(-1) level in tap and mineral water. The method is based on the direct introduction of samples, without any chemical pre-treatment, into an inductively coupled plasma mass spectrometer (ICP-MS). Uranium was determined at the mass number 238 using Rh as internal

ICP Waters — an International Programme for Surface Water Monitoring
Water, Air, and Soil Pollution, 2001The International Cooperative Programme on Assessment and Monitoring of Acidification of Rivers and Lakes (ICP Waters) was established in July 1985 under the United Nations Economic Commission for Europe (UN/ECE) Executive Body of the Convention on Long-Range Transboundary Air Pollution (LRTAP).

Water is a valuable commodity even where it is abundant, and its quality in respect of dissolved or suspended material is of great importance in many areas. The need for care with water destined for human consumption is obvious, in an age where the contamination of water supplies by human activity is all too common.

On-site environmental water analyses by ICP-MS
Science of The Total Environment, 1995Abstract ICP-MS analyses on drinking and vadose waters were performed on-site at a disused industrial/mining site in the former DDR. The results indicate the viability of performing on-site analyses of matrix samples for heavy metals while maintaining precision and accuracy better than other conventional techniques such as potentiometric stripping ...

Spectrochimica Acta Part B: Atomic Spectroscopy, 2021
Abstract Simple concepts that control the amount of analyte, solvent aerosol and solvent vapor that enter the plasma are used to explain changes in analyte transport efficiency as a function of sample uptake rate in pneumatic nebulizer/spray chamber sample introduction systems.

Determination of rhenium traces in river water by Q-ICP-MS and HR-ICP-MS
Journal of Radioanalytical and Nuclear Chemistry, 2003A simple separation method was applied to determine rhenium in river water using Q-ICP-MS and HR-ICP-MS. Re was concentrated from 420-925 ml river water using a TEVA resin minicolumn. Such extraction using a resin could separate Re from most sample matrices and trace elements.

Determination of water-soluble and insoluble elements in PM2.5 by ICP-MS
Science of The Total Environment, 2014The elemental composition of water-soluble and acid-soluble fractions of PM2.5 samples from two different Greek cities (Patras and Megalopolis) was investigated. Patras and Megalopolis represent different environments. Specifically, Patras is an urban environment with proximity to a large port, while Megalopolis is a small city located close to lignite

Determination of gadolinium in river water by SPE preconcentration and ICP-MS
Talanta, 2004An analytical scheme was developed for the determination of Gd-diethylenetriaminepentaacetate (Gd-DTPA), Gd and the other rare earth elements (REE) in river water by inductively coupled plasma (quadrupole) mass spectrometry (ICP-Q-MS). The preconcentration step was essential, since the limits of detection of this multielemental analytical technique are

Three different types of ICP-MS instrument, a quadrupole, a single collector magnetic sector and a multi-collector magnetic sector instrument, were compared for the measurement of Cu in a water sample by ICP-IDMS. Identical samples were run on the different instruments and various dilution levels were tested.

A study of transport and mixing in natural waters using ICP-MS: Water-particle interactions
Water, Air, & Soil Pollution, 1997Water-particle interactions often may result in non-conservative chemical behavior when waters from different sources mix with one another. The results presented in this paper address the role of these interactions in freshwater and estuarine mixing and support a larger study to develop a method to help resolve flow distribution and water quality ...
