Scientists from the University of Münster (Michael Sperling and Uwe Karst) have edited a collection of papers dedicated to speciation analysis. The issue is meant to give an overview over recent advances, hot topics and trends in speciation analysis.
Special issue:
The special issue published in "
Trends in Analytical Chemistry" is a collection of invited reviews by renowed scientists being active in the field of speciation analysis. In their editorial, the editors give a brief review about the importance of speciation analysis and its development over the last 50 years. During the development of speciation analysis, the use of techniques has been shifted from primarily atomic spectrometry to detect elemental species separated by different chromatographic and non-chromatographic separation techniques towards mass spectrometry.
Maria Montes-Bayon et al. from the University of Oviedo presents an overview of the use of elemental and molecular mass spectrometry as the tools for speciation analysis. The group of authors clearly show the trend to apply molecular mass spectrometry supported by software search engines to monitor elemental tags and to extract the structural and quantitative information by combined use with elemental mass spectrometry. Philip Doble et al. is reviewing chromatographic separation techniques coupled with ICP-MS, discussing
their intrinsic features that must be considered when designing
speciation experiments.
These authors also expect that future developments in mass spectrometry
(ICP-QQQ-MS, ICP-TOF-MS) will further improve the versatility of ICP-MS
for speciation analysis.
Franceso Porcaro et al. give an overview of synchrotron-based techniques for elemental speciation in biomedical research. Special attention is paid to metal-based drug biotransformation, metal and nanoparticle toxicology, and elemental speciation in cancer, neurological, and general pathophysiology. Justyna Wojcieszek et al. discuss the challenging speciation analysis of technology-critical elements (TCEs): Ga, Ge, In, Nb, Ta, Te, Tl, and most of the platinum group elements (PGEs) and rare earth elements (REEs) that occur at the low trace levels. Fabienne Seby and Veronique Vacchina present a synopsis of methods for the analysis of chromium species in different solid samples (soils/wastes, working atmosphere, industrial and food samples) paying particular attention to possible interconversion and methods to avoid or correct for this.
Sara Gutierrez Sama et al. review the speciation analysis of crude oils and heavy petroleum fractions, discussing the important role of high-resolution mass spectrometry to overcome the lacking selectivity of chromatographic separation which is necessary to investigate the metal speciation in crude oil beyond the simple porphyrins. Ghaya AlChoubassi et al. review the state-of-the art of methods for iron speciation in plant samples.
They show that dual separation-mechanism (SEC and HILIC) HPLC with dual
ICP MS and ESI MS detection provide a comprehensive speciation of low molecular weight iron
complexes in micro- or nanolitre volumes of plant fluids. Katarzyna Bierla et al. are critically discussing the recent advances in selenium speciation
analysis, especially in terms of sensitivity and specificity of ICP-MS
and electrospray-MS. Zuzana Gajdosechova et al. summarize the state of the art of current analytical techniques, focusing on the interactions between mercury and selenium in biological matrices.
Holtkamp and Hartinger are discussing some novel analytical Metallomics methods utilizing mass spectrometric detectors often hyphenated with separation systems, and their application to anticancer metallodrug research. Their emphasis is on the value of speciation analysis for the development of new anticancer agents with improved efficacy. Balazs Klencsar et al. review the current status of (U)HPLC-ICP-MS(/MS) for the analysis of drugs not containing a metal. Besides the possibilities to monitor the most important (non-metal) hetero-elements in pharmaceuticals, the reviewers also discuss derivatization strategies for drugs lacking an element detectable by ICP-MS.
David Clases et al. discuss current issues and developments regarding the role and the
analysis of metal species used as contrast agents in radiology and nuclear medicine. Laura Cid-Barrio et al. review the reliable and direct protein and peptide quantification with ICP-MS that nicely complements the structural information provided by molecular mass spectrometry in proteomics. Michalke et al. evaluate recent speciation findings in neurodegeneration research, concentrating on measurements in cerebrospinal fluid and brain tissue. The enhanced information obtained by speciation analysis allows discriminating less important species from compounds significant for the disease. Qing-qing Liu et al. summarize recent advances in speciation analysis of phenylarsenicals. HPLC coupled to ICP-MS and ESI-MS has enabled the identification and quantification of metabolites and improved our understanding of the fate of phenylarsenicals and the potential risk of human exposure. Finally, Julia Bornhorst et al. review the situation of adequate biomarkers for the trace element
species of Se, Mn, Zn and Cu and conclude that there is only a limited
understanding of putative interactions between the trace elements.
The editors express their hope that these 16 reviews by prominent groups from the field of
speciation analysis provide an overview of recent developments and
give an outlook for future directions.
