New Strategy for Speciation Analysis of Gadolinium retained in Bone after Application of MR Contrast Agents
( 16.09.2021 )
Researchers from Germany and France have developed a strategy to obtain information about gadolinium species that degrade during extraction from bone tissue. ...

On-column internal standardisation as an alternative calibration strategy for speciation analysis
( 27.08.2021 )
Researchers from LGC Ltd. (UK) developed a calibration method for speciation analysis using chromatographic separation that can correct for on-column analyte losses and signal drift and can be applied...

Arsenic Species in Seaweeds Commercially Available in the United States
( 16.08.2021 )
Researchers from U.S. FDA have analysed 46 seaweed samples purchased from the U.S. market for total arsenic and arsenic speciation. Arsenosugars were dominant in most seaweeds, inorganic arsenic did n...

Iron species determination by high performance liquid chromatography coupled with plasma source atomic emission spectrometry
( 14.08.2021 )
Researchers from Poland have compared microwave induced plasma optical emission spectrometry (MIP OES) and inductively coupled plasma optical emission spectrometry (ICP OES) for the detection of iron ...

Determination of Vitamin B12 in human milk
( 10.07.2021 )
Researchers from the Nestlé Research Laboratories have presented a new accurate and robust method for quantification of vitamin B12 in human milk. The method is based on a highly specific sample prepa...

Ultratrace determination of methylmercury in seawater using automated GC-AFS
( 08.07.2021 )
Researchers from the IAEA Environment Laboratories in Monaco have developed a highly automated method for the ultratrace determination of methylmercury in seawater. The developed method was optimized ...

Chromium speciation analysis in bread and breakfast cereals
( 07.07.2021 )
Researchers from France and Denmark now aimed at clarifying conflicting results for the presence of hexavalent chromium in bread and breakfast cereals. Using highly selective separation by HPLC couple...

Tellurium Speciation Analysis of Soil Samples Taken from an Area Associated with the Storage, Processing, and Recovery of Electrowaste
( 16.06.2021 )
Polish researchers developed, optimized and validated a method for the determination of inorganic ionic Te(VI) and Te(IV) forms in easily-leached fractions of soil by Ion Chromatography-Inductively Co...

Speciation analysis of rhenium by capillary electrophoresis-inductively coupled plasma mass spectrometry
( 14.06.2021 )
A group of Chinese researchers developed a method for the speciation of rhenium using the hyphenated technique of capillary electrophoresis-inductively coupled plasma mass spectrometry. Since the rhen...

Speciation analysis of gadolinium retained in the rat brain after administration of gadolinium-based contrast agents
( 13.06.2021 )
A group of French researchers developed a method for enhancing the poor extraction of retained gadolinium from brain tissue. Subsequent analysis using size exclusion chromatography–inductively coupled...
