Sample analysis method and sample introduction device
A desolvation unit performs desolvation by heating after a sample solution is turned to sample mist by a nebulizer. A sample gas that contains the desolvated sample mist and a carrier gas is introduced through a sample introduction tube to a plasma torch. An addition unit for adding, to the sample introduction tube, a water-containing gas is provided. The addition unit includes a container that contains ultrapure water, a gas tube for introducing the carrier gas into the ultrapure water to cause bubbling, and a gas tube for adding the water-containing gas, to the sample introduction tube. The plasma torch generates an inductively coupled plasma under the condition that supplied power is set to a range of 550 W to 700 W. Generation of interfering molecule ions due to an element having a high ionization potential is inhibited when an element in a sample ionized by the plasma is analyzed.

MATERIAL SYNTHESIS TECHNOLOGY BY MICROWAVE PLASMA TORCH WITH ATMOSPHERIC PRESSURE AND HIGH TEMPERATURE
The invention is for a material synthesis technology by microwave plasma torch with atmospheric pressure and high temperature. It includes a plasma torch system with atmosphere pressure & high temperature and a material growth system. In the plasma torch system the cutting-edge breakdown happens by inputting the high power microwave. Then the stable plasma torch with atmosphere pressure & high temperature generates under the avalanche effect of the cutting-edge breakdown by the solid precursor at the open-end of the cylindrical metal tube or the precursor carrier gas through the cylindrical metal tube. The result is that the precursors are decomposed and generates the active particles for material growth. In the material growth system the motion and ingredients proportion of negative and positive ions or particles in the active particle beam are controlled by the adjustable static electric field generated by the metal ring and the igniting & control electrode connecting to the external adjustable DC source. And the material growth space is heated by the heating system for the material growth. Then the material controlled growth is implemented by the heating system and the adjustable static electrical field.
