Direct analysis of wines from the province of Lower Silesia (Poland) by microplasma source optical emission spectrometry

Fast and simple analysis of the content of Zn, Mg, Ca, Na, and K in selected beverages widely consumed by athletes by flowing liquid cathode atmospheric pressure glow discharge optical emission spectrometry

“…These values are similar or slightly worse compared to that obtained by our group in previous studies. 28,29 The small differences between the DLs obtained in these three works likely resulted from the slightly different operating conditions (which affected not only the signal intensities but also the background level in the vicinity of the analytical lines) as well as tubes of different diameters applied in this work, which we know from our expercience to slightly affect the signal intensities. Comparing the obtained DLs of Zn, Mg, Ca, Na, and K with the values reported by other researchers for similar FLC-APGD systems (see Table 1), it can be noticed that the DLs of the elements obtained herein are on average 1 order of magnitude better than those published in the majority of recently published papers.…”

“…30,31 Moreover, similar to ICP-OES, FLC-APGD-OES enables the analysis of the content of many different elements in samples. 32–35 Owing to all these advantages, the FLC-APGD-OES method has been successfully applied for the analysis of different samples with complex matrices, such as blood, 36 honey, 37 human hair, 38 fruit juices, 28 soils, 33 and wines 29 as well as samples with simpler matrices such as different types of water. 39–45…”

“…Although the DLs of elements obtained with this system are not the highest (the FLA-APGD system offers signicantly lower DLs but for a limited group of elements, i.e., Ag, Bi, Cd, Hg, In, Pb, Tl, and Zn), they are still comparable to or better than that offered by atomic absorption spectrometry (AAS) and ICP-OES. [27][28][29] Alternatively, in the FLA-APGD-OES method, matrix effects are not oen observed and even if they are present, their extent is acceptably low. 30,31 Moreover, similar to ICP-OES, FLC-APGD-OES enables the analysis of the content of many different elements in samples.…”

[39][40][41][42][43][44][45] The costs involved in the application of large-scale commercial instrumentation such as ICP-OES vary depending on several factors, including the specic instrument being used, the cost of consumables (e.g., plasma gas, nebulizer, and pump tubing), and the cost of electricity.…”

A novel solution cathode glow discharge geometry for improved coupling to optical emission spectrometry

“…The SCGD has been used to quantitate elemental composition at trace and ultra-trace levels in a wide variety of sample types including silica colloids, 9 nanoparticles, 10 bottled water, 11 wastewaters, 12 honey, 13 and wine. 14 It has also found use with hydride generation, 15 water remediation, 16,17 and nanoparticle synthesis. 18 Because the SCGD-AES is a relatively nascent technique, a variety of methods and geometries have been reported to improve the analytical gures of merit of the technique.…”
