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

► We have optimized the performance of a lab-made CMA for the generation of metallic volatile species. ► 8-hydroxyquinoline was used as a reaction media to improve volatilization. ► The performance of the system was compared with the use of a forced outlet gas-liquid separator. ► There was an improvement of the detection limits when generating the volatile species of Ag, Au and Sn. ► The interface between the spray chamber and the ICP torch was a key point in the analysis.
