Direct determination of arsine in gases by inductively coupled plasma–dynamic reaction cell–mass spectrometry

Dynamic reaction cell ICP-MS for determination of total As, Cr, Se and V in complex matrices: Still a challenge? A review

“…The benefit of using O 2 in the DRC is in its ability of quantifying the specie 75 As 16 O + at mass 91, which is totally free of chloride-based polyatomic interferences, and gaining in sensitivity [67]. Direct determination of trace arsine in gas samples was achieved by determining arsenic as AsO, thus minimizing risks for species conversion during sample capturing and pretreatment [68]. Arsenic in blood was also successfully quantified at mass 91 after microwave digestion of samples.…”

“…However, the strong isobaric interference from 67 Zn can hamper a reliable quantification of V as oxide. Using a mathematical correction equation for 68 Zn may overcome this interference, but the real limit of this method could be the detection of V at very low concentration [75].…”

Development of amperometric arsine gas sensor using gold-modified diamond electrodes

“…Several methods have been reported for the detection of arsine, including physical methods [3][4][5][6], electrochemical methods [7][8][9][10], chemiluminescence [11] etc. Electrochemical detection based on gold electrodes was reported to show excellent selectivity against some interference gases, including hydrogen and vapor of organic solvent that are used in industrial processing and manufacturing [8].…”

Arsine adsorption in copper-exchanged zeolite under low temperature and micro-oxygen conditions

“…For instance, the permissible exposure limit of AsH 3 should be between 0.016 mg m À3 and 0.001 mg m À3 , which has been dened by the American Committee of government in Health and the Ministry of Environmental Protection of the People's Republic of China, respectively. 9 Furthermore, synthesis gas can be used to produce C1 chemical products with the development of C1 chemical technology. However, the most important factors of synthesis catalyst poisoning is the existence of many impurities such as sulfur, phosphorus, arsenic, and cyanide in synthesis gas.…”
