Determination of Unknown Organic-Metal Complexes in the Environment by Liquid Chromatography–Inductively Coupled Plasma-Mass Spectrometry
( 14.05.2023 )
A group of U.S. scientists have developed a quantitative method for the determination of metal complexes with dissolved organic matter (DOM) in the environment. The method is using an LC-ICP-MS appro...

Chemical vapor generation as a sample introduction technique for speciation analysis
( 12.05.2023 )
There are several techniques for speciation analysis that rely on elemental detection using atomic spectrometry, along with a separation technique to differentiate between different species. For liqui...

Identification of Monomethylmonothioarsonic Acid as the Major Thioarsenical Generated During Extraction of Arsenic Species from Rice
( 12.04.2023 )
Japanese researchers studied the arsenic species transformation during acid extraction of rice. They identified monomethylmono-thioarsonic acid as the major product generated from monomethyl-arsoni...

The long-term stability of arsenic species in certified reference materials NMIJ CRMs 7901-a, 7912-a, and 7913-a
( 02.04.2023 )
The stability of the arsenic compound standard solutions currently supplied by the National Metrology Institute of Japan (NMIJ) (CRM 7901-a arsenobetaine (AsB), 7912-a As(V), and 7913-a dimethylarsini...

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 ...
