Welcome to the January issue of EVISA's Speciation Newsletter !
The coupling of liquid chromatography with inductively coupled plasma-mass spectrometry (LC-ICP-MS) is the most often used technique for speciation analysis. At first sight this coupling seems to be straightforward by just directing the column effluent towards the nebulizer of the sample introduction system of the ICP-MS. However, the higher the resolving power of the LC system, the more critical is the dispersion introduced by the sample introduction system. The post-column dispersion is leading to peak broadening or even re-mixing, and is introduced by the dead-volume of the transfer capillary, the nebulizer and the spraychamber. A group of Chinese researchers now presented a new system for coupling LC with ICP-MS avoiding such dispersion by using a self-constructed direct injection nebulizer harboring the capillary column as the sample capillary (see the News below).
Another topic in LC-ICP-MS is the obtainable precision and accuracy often limited by matrix effects, plasma instability or signal drift. One solution to reduce such effects is the use of internal standards, an approach most often used for stand-alone ICP-MS methods. A group of Japanese researchers have now designed a technique for the online addition of an internal standard for HPLC-ICP-MS. An autosampler was used to load sample and internal standard onto the separation column. The authors could demonstrate that the use of Re as internal standard improved the accuracy of the As speciation analysis with HPLC-ICP-MS by compensating for the analytical bias and reducing the measurement uncertainty (see the News below).
The determination of the herbicide Glyphosate is most often performed by LC-MS/MS using ESI-MS for detection. An Italian group of researchers have developed a method using ICP-MS/MS for detection. The authors demonstrated that their method calls for less sample preparation, has a higher sample throughput and provides comparable detection power (see the News below).
The next event of interest for the speciation community is the European Winter Conference on Plasma Spectrochemistry (EWCPS2023), taking place January 29th to February 3rd, 2023 in Ljubljana, Slovenia. The conference is scheduled to have two sessions on speciation analysis.

NEWS

EVISA is keeping you updated with what is going on in speciation analysis. In this section you will find news about the most current research results, about trends, legal issues and information from manufacturers in the field of speciation analysis.
Unfortunately, this month we have not seen any publication related to speciation analysis of general interest. In case that you feel that we missed something, we would be happy to receive a notification.
With all the links to further information and publications the News archive is a valuable collection of "hot topics" in speciation analysis. We continuously update even former news with new links and information so that all news are actual all the time.
Online addition of an internal standard for high performance liquid chromatography-inductively coupled plasma mass spectrometry
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) making use of an autosampler system.

Determination of Glyphosate in Rice with HPLC-ICP-MS/MS
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
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 limit of detection (LOD) of ICPMS.
