Method Validation for the Determination of Mercury, Cadmium, Lead, Arsenic, Copper, Iron, and Zinc in Fish Through Microwave-Induced Plasma Optical Emission Spectrometry (MIP OES)

On a single method for determining As and Hg in dietary supplements by CVG-MIP OES: optimization of the multimode sample introduction system

“…Comparing the limits of detection (LODs) achieved for As and Hg in this work with previous reports in the literature (Table S3, ESI†), the value for As (0.3 μg L −1 ) was better than that reported by Machado et al 35 (0.46 μg L −1 ), Gallego Ríos et al 34 (2.0 μg L −1 ), and Zubricheva et al 33 (11 μg L −1 ). The LOD obtained for Hg (0.9 μg L −1 ) was better than 1.3 and 2.0 μg L −1 reported by Zubricheva et al 33 and Zhao et al , 37 but higher than 0.2 and 0.3 μg L −1 by Gallego Ríos et al 34 and Lima et al , 36 respectively.…”

“…Nowadays, coupling with most instruments has become easier with the use of a multimode sample introduction system (MSIS), allowing the simultaneous determination of volatile species-forming elements by CVG, as well as the possibility of elemental determination by conventional nebulization. 28 This coupling has been used for the simultaneous determination of As and Hg in pharmaceutical 33 and fish 34 samples, and also for the determination of As in agricultural samples, 35 and Hg in inorganic fertilizers 36 and in leather and fur. 37 However, the coupling of CVG-MIP OES using MSIS has not been demonstrated to date for the simultaneous determination of As and Hg in dietary supplements.…”

Analytical Methodologies for Agrometallomics: A Critical Review

“…However, due to relatively lower absolute temperature of excitation source, MP-OES is difficult to emit more atomic spectra compared with ICP-OES, which leads to the weaknesses for anti-interference and LOD. 63 Even so, MP-OES is completely superior to flame atomic absorption spectrometry (FAAS) and partly comparable to ICP-OES and has been applied in various agricultural research fields such as environmental, 64 plant, 65 agri-food, 66 health, 67 and biotechnology. 68 Besides, Duan et al fabricated a novel MP-OES of which microwave plasma was employed for surface sampling elemental analysis.…”
