Speciation News

Chromium speciation by magnetic solid phase extraction on-line with inductively coupled plasma optical emission spectrometry
( 13.03.2023 )
A group of Spanish researchers have developed a method for the speciation analysis of chromium based on solid phase extraction using a magnetic sorbent. ...

Determination of Thallium Species in Food Samples by Microextraction and Graphite Furnace Atomic Absorption Spectrometry
( 11.03.2023 )
A group of Chinese researchers have developed a method for thallium speciation analysis based on separation by single-drop microextraction. ...

Arsenic species in edible mushrooms from central Europe
( 14.02.2023 )
A group of researchers from the University of Graz have investigated the arsenic speciation in the most popular cultivated and wild-grown edible mushrooms in central Europe....

Online addition of an internal standard for high performance liquid chromatography-inductively coupled plasma mass spectrometry
( 10.01.2023 )
A Japanese group of researchers has designed an online internal standard correction technique for high-performance liquid chromatography-inductively coupled plasma mass spectrometry (HPLC-ICP-MS) maki...

Determination of Glyphosate in Rice with HPLC-ICP-MS/MS
( 09.01.2023 )
An Italian group of researchers have developed a method for the determination of glyphosate in rice samples using HPLC-ICP-MS/MS that is simpler and faster than existing methods based on LC-ESI-MS/MS....

Zero dead-volume interface for coupling µHPLC to ICP-MS
( 04.01.2023 )
A group of Chinese researchers propose a new system for coupling µHPLC to ICP-MS. The new system avoids any post-column dispersion, maintaining the molecular resolution obtained on μHPLC and the ...

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...
