A sensitive and accurate quantitative method for the speciation of inorganic Hg2+ and methyl-mercury by ID-HPLC–ICP-MS has been optimised and implemented for marine fish samples. Quantitative extraction of Hg species was achieved using a 0.1% (v/v)

Metal speciation analysis in MLPs was carried out in two snails, Marisa cornuarietis and Pomacea bridgesi, in order to investigate them as possible sentinel organisms of heavy metal contamination. To carry out this study snails born in a non-contamin

Quantitative proteomics and absolute determination of proteins are topics of fast growing interest, since only the quantity of proteins or changes in their abundance reflect the status and extent of changes of a given biological system. Quantificatio

Speciation of different metal isoforms present in metallothioneins (MTs) of living organisms requires both a high efficiency separation technique, e.g., CE, and a multielement, specific and highly sensitive detector (e.g. ICP-MS). To cope with natura

The role that different eel liver MT isoforms could play in metal sequestration was investigated here by “post-column” isotope dilution analysis (IDA) coupled to ICP-MS. Specimens of European eel (Anguilla anguilla) were exposed in aquarium tanks

Several complementary separation mechanisms (size-exclusion chromatography, SEC; fast protein liquid chromatography, FPLC; reverse-phase chromatography, RPC) have been coupled to inductively coupled plasma mass spectrometry (ICP-MS) detection to inve

Ga(III) and In(III) react with 7-iodo-hydroxyquinoline-5-sulphonic acid (Ferron) in the presence of CTAB micelles, forming complexes which exhibit analytically useful room-temperature phosphorescence (RTP). The RTP features of the two complexes are s

The Ga(III)-7-iodo-8-hydroxyquinoline-5-sulfonic acid complex in the presence of suitable micelles and with sodium sulfite as oxygen scavenger exhibited strong phosphorescence at room temperature in aqueous solutions. This micellar reaction provides

In the last decade mass-spectrometry-based proteomics has become an indispensable analytical tool for molecular biology, cellular biology and, lately, for the emerging systems biology. This review summarises the evolution and great potential of analy
