Analytical performance of a lab-made concomitant metal analyzer to generate volatile species of Ag, Au, Cd, Cu, Ni, Sn and Zn using 8-hydroxyquinoline as a reaction media

Efficient generation of volatile species for cadmium analysis in seafood and rice samples by a modified chemical vapor generation system coupled with atomic fluorescence spectrometry

“…This synergistic effect has also been obtained between TU and other transition metal ions, such as iron and nickel. These are in good agreement with previous results [20][21][22][23].…”

“…Guo and Guo [20] pointed out that thiourea (TU) and cobalt could greatly improve the generation efficiency of Cd. This synergistic effect has also been found between thiourea/8-hydroxyquinoline and other transition metal ions, such as iron and nickel [21,22]. We also reported that the efficiency of Cd electrochemical vapor generation can be highly increased by using organic media (HCOOH) as electrolytes [11].…”

Influence of Surfactant and Ionic Liquid Media on Vapor Generation and Determination of Ag, Au, Cd, Cu, Ni, Sn, and Zn Using ICP-OES

“…However, there is an increasing interest in the simultaneous determination of hydride-forming elements and non-hydride-forming elements using spray chambers as the gas liquid separator (40). There are also special commercial devices designed such as the Multimode Introduction System (41)(42)(43)(44) or the Concomitant Metal Analyzer (45,46). The present method can be used to measure simultaneously seven elements, and could be modified also to improve the performance of the individual elements using the optimum conditions for each element.…”
