Measuring actinium-227 by mass spectrometry is feasible, sensitive and reliable!
Levier and co-authors have developed a new protocol measurement of the dissolved actinium in seawater.

On the optimal use of the seaFAST system
Do you wish to improve your recoveries, blanks or any other parameter of your seawater preconcentration system (seaFAST)? Or are you simply curious about it? Wuttig and co-workers (2019, see reference […]
Analyzing rapidly, precisely and semi-automatically lead isotopes on variable volumes of seawater (up to 1000 ml)
Zurbrick and co-authors present a relatively fast (2.5–6.5 hours), semi-automated system to extract lead (Pb) from seawater, with few chemicals yielding low blanks. They also demonstrate that subsequent Pb isotopic […]
New method for measuring simultaneously trace metal concentrations on a very small volume of seawater
An automated, on-line extraction, flow-injection inductively coupled plasma mass spectrometry (ICP-MS) method is presented by Lagerström and co-authors for simultaneous determination of manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), […]
Determining simultaneously iron, zinc and cadmium isotopes in small volumes of seawater is possible now!
The first simultaneous method for the determination of these three isotope systems in seawater has been published. This method is designed for use on only a single litre of seawater […]
Latest recommendations for successful analysis of dissolved osmium in seawater
Analysis of osmium in seawater presents complex challenges, linked to its very low (femtomolar) concentrations and multiplicity of possible oxidation states. Early insights were provided by Karl Turekian’s group at […]
Measuring precisely with only 40 ml of sample
It is now possible to measure precisely manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), cadmium (Cd), and lead (Pb) concentrations in seawater using only 40 […]
New strategy to evaluate trace element fluxes to the ocean from aerosols
Scientists participating in GEOTRACES have developed a new strategy to evaluate trace element fluxes to the ocean from aerosols (Hsieh et al, 2011). The new approach uses the common geochemical behaviour […]
