Résumé
A multiple channel-type concentric grid nebulizer (m-CGrid) was developed for realizing efficient online standard addition in inductively coupled plasma optical emission spectrometry (ICP-OES) without premixing of liquids before nebulization. The m-CGrid can nebulize two independent liquids without premixing due to a unique structure, having two independent liquid-flow capillaries inside a single nozzle and a grid screen (over 350 mesh per inch) placed on the hole of the nozzle. The grid acts as both a flow damper and sieve; two liquids are well-mixed with a gas flow in a small space just before the grid screen, and the mixture breaks up into small droplets by passing through the grid. The m-CGrid nebulizer provides almost the same or better spray performance compared with a conventional nebulizer, such as Meinhard nebulizer; the primary aerosols were much finer (D
