Claim:
1. A method for generating aerosol using an indirectly heated capillary aerosol generator, which comprises a capillary tube adapted to form an aerosol when liquid material in the capillary tube is heated to volatilize at least some of the liquid material therein, and a thermally conductive material in thermal contact with the capillary tube, wherein the thermally conductive material has a threaded exterior and is wrapped with a helically extending heating wire, which has electrical leads attached to it, and wherein the helically extending heating wire is disposed along thread grooves of the threaded exterior of the thermally conductive material with uniform spacing between turns of the helically extending heating wire, the method comprising: supplying energy to the thermally conductive material of the indirectly heated capillary aerosol generator; supplying liquid material to an inlet of the capillary tube; wherein sufficient energy is supplied to the thermally conductive material such that the thermally conductive material supplies sufficient heat to the liquid material in the capillary tube to volatilize liquid material in the capillary tube; wherein volatilized liquid material is driven out of an outlet of the capillary tube and mixes with air to form aerosol; and monitoring the temperature of the thermally conductive material with a thermocouple.
