Use and limitations of ICP-OES in wine analysis
Mikrochimica Acta, 1989At present, some 50 inorganic components in wine can be detected, of which 8 are mineral matter at concentrations down to 1 mg/l, about 25 are trace elements with concentrations of 0.001–0.1 mg/l, and about 20 are ultratrace elements at concentrations below 1 μg/1.

The application of ICP-OES to industrial analytical problems
TrAC Trends in Analytical Chemistry, 1982Abstract ICP optical emission spectroscopy was introduced for multi-element determinations some 15 years ago. Nowadays, its field of application covers the analysis of widely differing materials at every stage of industrial activity.

Sample introduction into ICP-OES for metallic samples
Mikrochimica Acta, 1989Two different methods of sample introduction into an ICP source have been applied to solve special problems of metal analysis. First, an electrolytical cell was used to dissolve the metallic compounds of metals only. The resulting analyte solution is flow-injected directly into the ICP.

Determination of Trace Elements in Turkish Wines by ICP-OES and HG-ICP-OES
2010The aim of this work was to determine the concentration of toxic metals in wine samples from different regions in Turkey using ICP-OES and HG-ICP-OES, and comparing the results with reports from other researchers. Ten samples each of white wines and red wines were obtained at a local supermarket and analyzed for Ca, K, Cr, Mn, Sn, Zn, Cu, Fe, Ni, Mg ...

Trace Element Determination Using ICP-OES
2022Inductively coupled plasma-optical emission spectroscopy coupled with the benefits of solution chemistry serves as an excellent tool in trace element analysis (TEA) because of its multielement capability, large dynamic range of four to six orders of magnitude, and very high temperature in the range of 7000–10 000 K resulting in virtually complete ...

Traceable Phosphorus Measurements by ICP-OES and HPLC for the Quantitation of DNA
Analytical Chemistry, 2007Measurement of the phosphorus content of nucleotides and deoxyribonucleic acid (DNA) offers an approach to the quantitation of nucleic acids that is traceable to the SI. Such measurements can be an alternative to the commonly used spectroscopic tools that are not traceable.

Continuous measurement of metals in flue gas using ICP-OES
Analytical and Bioanalytical Chemistry, 2003A system capable of continuously measuring a range of metallic elements in the effluent gas from incinerators and other similar industrial processes, and providing on-line results has been developed. With a state-of-the-art mobile laboratory measurements were taken from a UK municipal solid waste incinerator.

Physical interferences by mineral acids in ICP-OES
Journal of Analytical Atomic Spectrometry, 2000A study has been made of mineral-acid interferences in the trace element determination of Fe, Mn and Zn by inductively coupled plasma optical emission spectrometry. A number of solutions containing 50 µg ml−1 of analytes in acid concentrations of 0 to 50% (v/v) were used.

Fast method of elements determination in slim coffees by ICP OES
Food Chemistry, 2014Six sample preparation procedures, i.e., the total decomposition in a HNO3 and H2O2 mixture by microwave-assisted or hot-plate heating, a partial decomposition by means of solubilisation in aqua regia or tetramethyl ammonium hydroxide and simple dissolution in diluted HNO3 or in H2O, for the determination of the total content of Ba, Ca, Cd, Cr, Cu, Fe,
