In this review, a full discussion and update of the state-of-the-art of gas chromatography (GC) coupled to all known plasma spectrometers is presented. A brief introductive discussion of the advantages and disadvantages of GC–plasma interfaces, as well as types of plasmas and mass spectrometers, is given. The plasma-based techniques covered include inductively coupled plasma mass spectrometry (...

Vanadium is found in many rocks and minerals, including asphaltite. Asphaltite is one of the naturally occurring black, solid bitumens, which are soluble at heating in carbon disulfide and fuse. Asphaltite is also a solidified hydrocarbon compound derived from petroleum. Determination of vanadium in asphaltite ash was performed by microwave-acid digestion followed by inductively coupled plasma-...

This paper describes a novel approach for analysis of mercury speciation in fish using gas chromatography coupled with microwave-induced plasma optical emission spectrometry (GC-MIP-OES) in surfatron resonant cavity. Sample treatment was based on quantitative leaching of mercury species from fish tissue with ultrasound-assisted acidtoluene extraction. The extracted mercury species analyzed with...

Spectrometric techniques for the analysis of trace lead have developed rapidly due to the increasing need for accurate measurements at extremely low levels of this element in diverse matrices. This review covers separation and preconcentration procedures, and considers the features of the application with several spectrometric techniques. The use of an appropriate sample handling technique is a...

The potential value of an oscillating-mirror rapid-scanning spectrometer as a detector for simultaneous multi-element emission spectrometry is demonstrated. A microwave argon plasma was used as the emission source with a carbon cup sampling device for analyte introduction. Analy tical graphs for bismuth, cadmium, manganese and magnesium prepared sirnulta neously are shown. The sensitivity of th...

Nd-doped Si-rich silicon oxide thin films were produced by radio frequency magnetron co-sputtering of three confocal cathodes: Si, SiO2, and Nd2O3, in pure argon plasma at 500oC. The microstructure and optical properties of the films were investigated versus silicon excess and post-deposition annealing treatment by means of ellipsometry and Fourier transform infrared spectrometry as well as by ...

The isotopic composition of different materials can be imaged by secondary ion mass spectrometry. In biology, this method is mainly used to study cellular metabolism and turnover, by pulsing the cells with marker molecules such as amino acids labelled with stable isotopes ((15)N, (13)C). The incorporation of the markers is then imaged with a lateral resolution that can surpass 100 nm. However, ...

This paper reviews the current research on the speciation and determination of mercury by various analytical techniques, including the atomic absorption spectrometry (AAS), voltammetry, inductively coupled plasma optical emission spectrometry (ICP-OES), ICP-mass spectrometry (MS), atomic fluorescence spectrometry (AFS), spectrophotometry, spectrofluorometry, and high performance liquid chromato...
