Tin content in samples of canned fruits and vegetables was determined by hydride generation inductively coupled plasma atomic emission spectrometry (HG-ICP-OES), and it was compared with results obtained by standard method of flame atomic absorption spectrometry (AAS). Selected tin emission lines intensity was measured in prepared samples after addition of tartaric acid and followed by hydride ...

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...

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...

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-...

A remote detection system based on optical emission spectrometry of laser-induced plasmas has been developed to record spectra in the visible region from samples placed at remote distances from the excitation source. Unlike from fiber-optic-based systems, light collection is performed remotely as well. Laboratory-scale experiments have shown the possibility of performing real-time analysis of s...

A comparison between two analytical techniques commonly used for the determination of sulphur concentrations in natural water samples is reported. Significant differences in the sulphur values obtained using inductively coupled plasma atomic emission spectrometry and ion chromatography are described. The contribution of a sulphur fraction (presumed to be organic S) not detected by ion chromatog...

This paper focuses on heavy metal distribution patterns in sediments of central Guilan (CG) and east Mazandaran (EM) in the south Caspian Sea coasts, north of Iran. Sediment sub-samples were retrieved from core and surficial samples in different environments of marine and coastal lagoons as well as coastal outcrops. Inductively Coupled Plasma Mass Spectrometry and Atomic Emission Spectrometry (...
