Nebulizer gas flow

CLND Operational settings High Gas flow, nebulization, and vacuum strongly influence the response... 

The plasma torch consists of three concentric tubes, which are normally made from quartz. In Figure 4.2, these are shown as the outer tube, middle tube, and sample injector. The torch can either be one piece, in which all three tubes are connected, or it can employ a demountable design in which the tubes and the sample injector are separate. The gas (usually argon) that is used to form the plasma (plasma gas) is passed between the outer and middle tubes at a flow rate of 12-17 Lfinin. A second gas flow (auxiliary gas) passes between the middle tube and the sample injector at 1 L/min and is used to change the position of the base of the plasma relative to the tube and the injector. A third gas flow (nebulizer gas), also at -1 L/min, brings the sample, in the form of a fine-droplet aerosol, from the sample introduction system...
