Scientists use Laser Ablation-ICP to Study Eruption History

Posted by Betsey Seibel on Mar 14, 2018 1:42:15 PM

 

Scientists from the University of Queensland and Trinity College Dublin studied the most active volcano in Europe, Sicily’s Mount Etna, to better understand its eruption history. Currently, there is no way to predict volcanic eruptions, but tiny crystals formed prior to an eruption, may provide valuable evidence of the process that leads up to and the timing of volcanic activity, information that may help in building an early warning system.

Teledyne CETAC Announces World First in Elemental Bio-Imaging

Posted by Betsey Seibel on Jan 18, 2018 3:20:24 PM

 

analyte_excite.pngTeledyne CETAC and TOFWERK AG (Switzerland) recently announced the installation of the world’s first combination of an Analyte Excite excimer laser ablation system with HelEx II sample chamber and ARIS rapid aerosol introduction system coupled to an icpTOF 2R mass spectrometer at the University of Vienna. The system will be used for imaging element concentration distribution in biological samples, and will enable transmission of aerosol generated from laser pulses to the mass spectrometer in less than 30 milliseconds.

Is Lack of Innovation Causing Image Problem for Chemistry?

Posted by Betsey Seibel on Nov 1, 2017 8:43:33 AM

 

The chemistry industry has an innovation problem. At least that’s according to a survey of 186 chemists from academia and industry completed recently by Elsevier’s Reaxys, a web-based chemical data retrieval tool. An overwhelming majority (78%) of chemist surveyed felt that prospective chemists are going into other sciences because of the opportunity to participate in more “newsworthy” breakthroughs, while 80% felt that innovation was suffering because of an overemphasis on applied research.

Elemental Mapping of Teeth, Otolith and Banded Iron by Laser Ablation Inductively Coupled Plasma Mass Spectrometry

Posted by Betsey Seibel on Oct 26, 2017 9:03:06 AM

 

Trace element maps give unique insight to homogeneity, enrichment, and spatial distribution of elements in solid samples. Depending on the sample type, we can gain a wealth of information from sample maps beyond what is available from single or multiple spot analyses or single lines/rasters.  

Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) provides high spatial lateral resolution and can be used to construct trace element maps with minimal destruction of the sample. A study using LA-ICP-MS completed by Teledyne CETAC, Arkansas Biosciences Institute and Arkansas State University compiled and interpreted elemental maps for three distinct sample types: banded iron formation (BIF), human teeth and fish otolith.

Arsenic and Nitrates Contamination on the Rise

Posted by Betsey Seibel on Mar 17, 2017 3:16:51 PM

 

 

In late January 2017, the Department of Environmental Quality released a study of pockets of groundwater outside of Medford and Central Point, Oregon. Among the 107 wells tested, 21 percent had higher levels of nitrates, while four percent had higher than recommended health levels. Twenty-two percent of the wells contained arsenic and six percent had unhealthy levels. While the findings were lower than expected, the presence of nitrates and arsenic in drinking water raises a red flag for local residents.

Lead Remediation Plan 30-Years in the Making

Posted by Betsey Seibel on Feb 27, 2017 4:55:10 PM

 

From 1868 to 1988, the Geneva Foundry operated in Geneva, NY manufacturing cast iron components. According to historical records the site did not have pollution control on its smokestack until 1970. Even after that, the controls did not work as they should have. The foundry used recycled iron that contained lead and other metals while the furnaces burned coal containing arsenic and mercury. In 1986, a neighbor to the foundry complained to the New York State Department of Environmental Conservation about chemical drums that were leaking near their property. That complaint led to major contamination discovery 30-years later.
