Performance of a Dual Sample Introduction System with Conventional Concentric Nebulizers for Simultaneous Determination of Hydride and Non-Hydride Forming Elements by ICP-OES
Autor: Zully Benzo, Domingo Maldonado, C. Gomez, Manuelita Quintal, Janeth Salas, Eunice Marcano, José Chirinos
Publikováno v: Instrumentation Science & Technology. 36:598-610
A dual sample introduction system that combines the benefits of nebulization and vapour generation in a single device is described. It consists of two commercial conventional concentric nebulizers coupled to a modified cyclonic chamber. The effect(s)
