The Determination of Hexavalent Chromium in Airborne Particulate Matter in Presence of High Amounts of Trivalent Chromium
( 06.11.2022 )
Researchers from Italy and the UK developed a chromium speciation method for particulate matter that produces accurate results for Cr(VI) even in presence of high concentrations of Cr(III)....

Selenium May Play a More Important Role in Microbes Than Previously Thought
( 28.09.2022 )
The Mo Lab at the Departments of Chemistry & Molecular Biology of the Princeton University has discovered a biosynthetic pathway of microbes that incorporates selenium into small molecules, marking th...

A new server for EVISA's web portal
( 28.09.2022 )
While the EVISA server was running the last 20 years without any major failure, it was time to move to a more modern system. The main reason for updating our system was not its reliability but the lac...

EVISA's Internet Platform went online in September 2003. Since then more than 18 Mio. Users have visited the platform, actually more than 3500 per day. In average, every user is looking for more than ...

Quantitative determination of labile iron complexes by hydrophilic interaction liquid chromatography – electrospray MS/inductively coupled plasma mass spectrometry
( 13.09.2022 )
A group of scientists working at the University of Pau have developed a method for the quantitative determination of labile iron species using species-specific isotope dilution analysis. ...

New arsenic compound found in rice: dimethyl-arsonyl-dimethyl-arsinic acid
( 10.08.2022 )
A group of researchers from the TESLA Lab at the University of Graz together with a colleague from the US FDA have identified a former unknown arsenic species observed in some rice grain samples....

Determination of tungsten species in natural waters by HPLC-ICP-MS
( 08.08.2022 )
Chinese researchers have developed a method for the simultaneous determination of tungstates, thiotungstates, and polytungstates in natural waters by reverse phase ion pair chromatography coupled with...

Ultra-sensitive speciation analysis of inorganic platinum-chloride complexes in platinum-based drugs by HPLC-ICP-MS
( 14.07.2022 )
Chinese researchers have developed a method for the determination of platinum chloride complexes as impurities of platinum-based drugs. ...

1,2-Hexanediol as eluent for HPLC Enables Coupling with ICPMS under Standard Conditions
( 06.07.2022 )
Researchers from the University of Graz propose to use 1,2-Hexanediol as eluent for RP-HPLC coupled to ICP-MS. This eluent avoids the necessity to operate the ICP-MS in the organic mode improving the ...

Rapid automated arsenic speciation analysis by inductively coupled plasma mass spectrometry
( 01.06.2022 )
Using a commercial platform automation system, scientists from Elemental Scientific have developed methods for the total arsenic determination and its speciation in urine samples. The obtained results...
