Easy-to-use system developed to support ultralow detection limits, and has improved interference removal capabilities. Users can switch between single and triple quadrupole modes within a single multi-element experiment. The instrument requires minimal user maintenance and includes QCell flatapole technology, a small volume collision/reaction cell with flatapole rods, and a dedicated gas...
This work builds on our previous study of arsenic species in apple juice by incorporating several improvements to the methodology and exploring the analysis more deeply.
PerkinElmer's new ICP-MS system
This article is is a fascinating look into the use of laser ablation inductively coupled plasma mass spectrometry in forensic examination of glass fragments. These are often associated with crime scenes and easily “attach” to any people near them. Thus, they can be used to link criminals to their crime and to provide information on where a glass fragment might have originated.
Agilent Technologies introduced the second-generation, 8900 triple quadrupole ICP-MS system.

Photonis USA has announced that it has reached an agreement with MasCom Technologies GmbH of Bremen, Germany, to stock and resell a wide selection of discrete dynode electron multipliers designed for use in inductively coupled mass spectrometry (ICP-MS) instruments. The agreement adds to Photonis’ extensive line of electron multiplier products.
Stanislav Strekopytov tells us about “The use of inductively coupled plasma mass spectrometry to quantify chemical hazards in natural history collections: arsenic and mercury in taxidermy bird specimens”. It is quite shocking to learn about the use of poisons to preserve taxidermy specimens in the past. Nowadays it is essential that the dangers from such specimens are known before they can be...
Unique “graffiti” on the walls of a cave in central China describes the effects drought had on the local population over the past 500 years. Stable isotope and elemental analysis of stalactites have been able to confirm the climate variations.
Sotiris Stasinos and Ioannis Zabetakis have used ICP-MS to investigate the cross-contamination of food crops by heavy metals in ground or irrigation water. They show that this can occur easily in certain crops, which has serious health consequences for those consuming the food crop. As a consequence of their work, the European Food Safety Authority (EFSA) has been informed about the...
Ecosystem indicator species such as earthworms have been employed as a tool for assessing soil contamination, in particular using bioaccumulation as a guide to a contaminant bioavailability. Whilst not directly indicating potential human health effects, the use of sentinel organisms such as earthworms may provide a useful surrogate to human studies at arsenic contaminated sites and provide a...
After the progressive development of techniques that yielded results for optimal samples, Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) has at last provided a means of analysing individual fluid inclusions in typical, rather than exceptional, samples. The first truly quantitative LA-ICP-MS analyses of single fluid inclusions were carried out in ETH Zurich in a group...
