Determination of arsenic species in human urine using high performance liquid chromatography (HPLC) coupled with inductively coupled plasma mass spectrometry (ICP-MS)

Simultaneous speciation of inorganic arsenic, selenium and tellurium in environmental water samples by dispersive liquid liquid microextraction combined with electrothermal vaporization inductively coupled plasma mass spectrometry

“…It is well known that arsenic (As) is a highly toxic metalloid that can induce skin, bladder, and liver tumors and it ranks first on the list of hazardous substances issued by the Agency for Toxic Substances and Disease Registry of the US Environmental Protection Agency [1][2][3]. Arsenic can exist in inorganic forms such as As(III), As(V) and organic forms such as monomethylarsonic acid, dimethylarsenic acid, arsenobetaine and arsenocholine.…”

Reversed Phase Column HPLC-ICP-MS Conditions for Arsenic Speciation Analysis of Rice Flour

“…The method has been used for rice flour, fish and shellfish, and biological samples that contain a range of arsenic species. [22][23][24][25][26][27][28][29][30][31][32][33][34] However, the peaks for As(III) and MMAA are very close together, as are those for DMAA and AsB, and TMAO and TeMA. If many analyses are carried out on one column, some degradation of the packing might occur and these pairs of peaks would possibly not be separated.…”

Speciation Analysis of Trace Inorganic Arsenic in Dietary Supplements by Slurry Sampling Hydride Generation Atomic Absorption Spectrometry

“…A variety of techniques used for the speciation and determination of inorganic arsenic were reviewed, and the advantages and applied fields of different methods were discussed (Muñoz and Palmero 2005;Kumar and Riyazuddin 2007;Zhu and Qin 2008;Rabieh et al 2008). The extraction procedure for each method is commonly a crucial step in speciation studies because no interconversion of species should occur.…”
