V-groove nebulizer

Suspensions were pretreated by soni-cation for 2D4 min. After sonication, the samples were diluted to 10 mL with water. Aerosols, produced from suspensions by the V-groove nebulizer, were immediately carried on by the Ar plasma support gas through the spray chamber into the plasma...

For many years pneumatic nebulizers of the V-groove, Meinhard and cross-flow type have been the most widely used sample insertion devices for aerosol generation. The interaction geometry between the gas and liquid sample streams allows pneumatic nebulizers to be classified into two major groups, namely (a) pneumatic concentric nebulizers, which involve concentric interaction and (b) cross-flow nebulizers, which involve perpendicular interaction between the liquid and gas streams. Pneumatic nebulizers are well established and widely used on account of their simplicity, robustness, ease of use and low cost however, they provide low transport efficiency and tend to be clogged by high salt-content solutions [4]. 

Figure 14.4 Nebulizers. Models cross flow (1), concentric (2) and parallel (3). In contrast to models 1 and 2, model 3 is not subject to particulate obstruction by impurities in the solution. They leave through a large capillary that drains hy gravity along a V-groove design to the outlet where the aerosol is produced (Babmgton nehulizer). For the solution, a pump regulates the flow of the aerosol. The chamber at the outlet of the nehulizer is used as a drain to eliminate the larger droplets hy gravity.
