Abstract
An ICP analyzer has a nebulizer for nebulizing a sample fluid for the purpose of analyzing microscopic impurities within the sample fluid, a plasma torch for introducing nebulized spray into a plasma, and a spray chamber disposed between the nebulizer and the plasma torch for separating spray comprised of microscopic particles from the nebulized spray prior to introduction thereof into the plasma torch. A heating section is provided at a central portion of the spray chamber and a cooling section is provided at a peripheral section of the spray chamber, and the spray is passed between the heating section and the cooling section to improve the efficiency sample introduction into the plasma to enable highly sensitive analysis by suppressing the proportion of a solvent component that reaches the plasma torch.
