Speciation analysis of selenium in rice samples by using capillary electrophoresis-inductively coupled plasma mass spectrometry

Solidified floating organic drop microextraction for speciation of selenium and its distribution in selenium-rich tea leaves and tea infusion by electrothermal vapourisation inductively coupled plasma mass spectrometry

“…The comparison of the analytical performances in this work with those reported in the literatures was given in Table S-3. As can be seen, this method offers higher enrichment factor and lower detection limits, but the relative standard deviations are comparable to those reported in the literatures (Corinne, Olivier, & Martine, 2002;Xia et al, 2006;Zhang, Duan, He, Chen, & Hu, 2013;Zhao et al, 2011).…”

DNA binding in combination with capillary electrophoresis and inductively coupled plasma mass spectrometry for the rapid speciation analysis of mercury

“…The data was obtained by determining 20 ng/mL mixed solution of Hg 2+ and CH 3 Hg + reported that the presence of carbon-containing compounds in sample solution can enhance the elemental signal in ICP-MS analysis [28,29]. In our method, the running buffer contained carbon-containing compounds, namely EDTA and CTAB.…”

Capillary electrophoresis determination of non-protein amino acids as quality markers in foods

“…An effective way for providing selenium is through the selenium-enriched foods intake. To carry out the nutritional and toxic evaluation of selenium compounds (Se (IV), Se (VI) and the non-protein amino acids selenocysteine (SeCys 2 ) and selenomethionine (SeMet)) in nutritional food supplements, Zhao et al [40] developed CZEinductively coupled plasma MS (CZE-ICP-MS) methodology. As it can be seen in Table 1, sample treatment included an enzymeassisted extraction approach to extract all selenium species and the CZE separation was accomplished using 20 mM sodium phosphate, 10 mM sodium borate and 0.2 mM cetyltrimethylammonium bromide (CTBA) as separation buffer (pH 8.6).…”
