<P>PROBLEM TO BE SOLVED: To provide an inductively coupled plasma torch in which a capillary tube is stably retained concentrically with a makeup gas tube, a makeup gas can be flowed smoothly and the position of the tip part of the capillary tube in the axial direction can be easily adjusted. <P>SOLUTION: An inductively coupled plasma torch assembly includes a makeup gas tube 3 receiving a capillary tube 4 introducing gaseous sample so as to enclose it and making the makeup gas to pass into a space between the capillary tube and itself, a cylindrical body for heating the makeup gas tube from outside, and a torch body 7, 8 holding the cylindrical body. The inductively coupled plasma torch assembly is provided with a positioning member 15 for positioning the capillary tube in the diameter direction on the tip side of the cylindrical body while allowing the makeup gas to pass, wherein the positioning member is fixed to the tip part of the cylindrical body. <P>COPYRIGHT: (C)2007,JPO&INPIT |
