Melt flow rate stabilisers

The torch consists of three concentric quartz tubes (Fig. 3.8). The plasma gas, introduced between the intermediate tube and the external tube at a flow rate of 12 to 201/min, feeds the plasma, stabilises it in the centre of the torch and cools the external tube in order to prevent it from deforming or melting. The carrier gas and the sample in aerosol form are introduced into the plasma via the injector along the axis of the torch at a flow rate of 0.5 to 1.5 1/min. A...
