Journal ArticleDOI
Heavy metals, trace elements and sediment geochemistry at four Mediterranean fish farms
Ioanna Kalantzi,Tracy M Shimmield,Spiros A. Pergantis,Nafsika Papageorgiou,Kenneth D. Black,Ioannis Karakassis +5 more
TL;DR: Trace element concentrations in sediment were investigated at four fish farms in the Eastern Mediterranean Sea and found that, in anoxic sediments, all elements had higher concentrations at the impacted stations than at reference stations while in oxic sediment, many elemental concentrations were lower at impacts than atreference stations.
Journal ArticleDOI
Mass Spectrometric Determination of the Sites of O-Glycan Attachment with Low Picomolar Sensitivity
Geert Jan Rademaker,Spiros A. Pergantis,Leonore Blok-Tip,James I. Langridge,Astrid Kleen,Jane Thomas-Oates +5 more
TL;DR: A sensitive protocol for unambiguously and positively identifying O-glycosylation sites in glycopeptides is described, based on beta-elimination of the glycan chain using NH4OH, and it is demonstrated that site determination can be achieved using as little as 1 pmol of starting material.
Journal ArticleDOI
Hydrodynamic chromatography online with single particle-inductively coupled plasma mass spectrometry for ultratrace detection of metal-containing nanoparticles.
TL;DR: This study reports on the development of a hyphenated analytical technique for the detection and characterization of metal-containing NPs, i.e., their metal mass fraction, size, and number concentration.
Journal ArticleDOI
High-speed separation of arsenic compounds using narrow-bore high-performance liquid chromatography on-line with inductively coupled plasma mass spectrometry
TL;DR: In this article, an octadecyldimethylsilyl reversed-phase narrow-bore HPLC column was used for the high-speed separation of several biologically and environmentally important arsenic compounds.
Journal ArticleDOI
Determination of Ten Organoarsenic Compounds Using Microbore High-performance Liquid Chromatography Coupled With Electrospray Mass Spectrometry–Mass Spectrometry
TL;DR: An analytical method based on reversed-phase microbore HPLC coupled with electrospray mass spectrometry (ES-MS) is described in this paper, which allows for the determination of up to ten organoarsenicals in a single chromatographic run.
