Solid-phase microextraction coupled with Atomic Emission Spectroscopy--rapid screening for volatile chlorinated compounds.
Chemosphere, 2002Co-Authors: Svein Ingar Semb, Stig Pedersen-bjergaard, Einar Magne BrevikAbstract:Solid-phase microextraction (SPME) coupled with Atomic Emission Spectroscopy was evaluated as a rapid screening tool for volatile halogenated compounds in water samples. After extraction, the SPME fiber was introduced to the injector where the analytes were rapidly and efficiently desorbed. The analytes entered the detector over a short period of time and produced one well-defined analyte signal. Element selective responses were measured to confirm the presence and to roughly estimate the content of volatile compounds. The total time for extraction and detection was approximately 5 min, which makes this method a rapid and promising technique for determination of total amount of volatile halogenated compounds. The proposed technique may prove useful as a screening test in order to pinpoint the samples that need further assessment by capillary gas chromatography.

Environmental screening by capillary gas chromatography combined with mass spectrometry and Atomic Emission Spectroscopy
Chemosphere, 1996Co-Authors: Stig Pedersen-bjergaard, Svein Ingar Semb, John Vedde, Einar Magne Brevik, Tyge GreibrokkAbstract:Capillary gas chromatography (GC) combined with mass spectrometry (MS) and Atomic Emission Spectroscopy (AED) was utilized for a comprehensive investigation of organic micropollutants in a marine sediment. Most compounds were found and identified by GC-MS library search. The elemental information from GC-AED was utilized for confirmation purposes, for analyte characterization in cases where identification by GC-MS was impossible, and for screening on heteroAtomic components. In addition, GC-AED was effectively used for the quantitative part, where the total amount of GC amenable material, classes of compounds, and individual components were determined.

chemical characterisation of ancient pottery from south of italy by inductively coupled plasma Atomic Emission Spectroscopy icp aes statistical multivariate analysis of data
Analytica Chimica Acta, 2000Co-Authors: P Bruno, M Caselli, M L Curri, A Genga, R Striccoli, A TrainiAbstract:Chemical characterisation has been carried out on 58 fragments of archaeological pottery from pre-classical sites in Apulia and Lucania, regions in southern Italy. Fourteen elements were determined by Atomic Emission Spectroscopy by using inductively coupled plasma source. Statistical techniques, such as principal component analysis and clustering analysis, have been utilised to define grouping of different pottery items. Tests performed showed that the analysed shards were differentiable mainly by age and provenance.

Continuous flow quantification of total mercury in whole blood, plasma, erythrocytes, and urine by inductively coupled plasma Atomic Emission Spectroscopy.
Journal of analytical toxicology, 1992Co-Authors: F. Buneaux, A. Buisine, S. Bourdon, R. BourdonAbstract:Mercury determination in blood and urine can be performed by inductively coupled plasma Atomic Emission Spectroscopy (ICPAES) after dilution in an ammonia buffer and reduction by sodium borohydride. The proposed method does not need an oxidative mineralization. The sample is not nebulized into the torch, but the mercury vapor, after collection in a reactor vial, is swept into the plasma by the argon carrier gas using the described glass apparatus.
