PROBLEM TO BE SOLVED: To provide an ICP analyzer stably introducing a sample solution into a plasma torch without causing pulsation regardless of the sample solution, not only to suppress the change with an elapse of time caused by the consumption and deterioration of a tube, but also to reduce the cause of noise. SOLUTION: This ICP analyzer is constituted so that gas G is introduced into a sample container 21 under pressure to pressurize the liquid surface 2a of the sample solution 2 in the sample container 21 to supply the sample solution 2 to a nebulizer 3 through a liquid supply pipe 22 by this pressurizing force (f) and the sample solution 2 is sprayed into a spray chamber 4 by the nebulizer 3 to introduce the sprayed sample solution 13a into the plasma torch 1 while the component element of the sample solution 2 is analyzed using inductive coupling high-frequency plasma discharge. Further, the pressurizing force F is adjusted corresponding to the viscous degree of the sample solution 2. COPYRIGHT: (C)2005,JPO&NCIPI
