ABSTRACT:
To provide an inductively-coupled plasma torch capable of realizing a GC analysis or the like and a solution analysis by the same torch without removing a capillary tube, etc. The injector tube of the inductively-coupled plasma torch includes an outer injector tube11for introducing an atomized solution sample or the like into the inductively-coupled plasma, and an inner injector tube12for introducing gaseous molecules into the inductively-coupled plasma, housed in the outer injector tube as integrated and coaxially with it. The inner injector tube is able to convey make-up gas, and has a capillary tube4for conveying gaseous molecules and carrier gas together. For sample introduction in analyzing a gaseous sample, the inner injector tube12is used, and for sample introduction in analyzing an aerosol sample, the outer injector tube11is used.
