PURPOSE:To enable the use of an inexpensive monochromatic meter by arranging a plasma torch having a plasma light inductively excited by a high frequency, a vaporizer for vaporizing a sample to be introduced thereto and the like. CONSTITUTION:A plasma emission analyzer has a plasma light emission source (plasma torch) 1 inductively excited by a high frequency and a sample vaporizer 2 connected to the plasma 1 through a hollow pipe 3. A mobile reflector 10 is inclined toward the solid line to focus light from a hollow cathode discharge tube 11 onto an inlet slit 7 through a concave mirror 4 and a flat mirror 5. Then, a grating 8 is driven with a pulse motor 9 to detect a light 13a emitted from iron existing the closest vicinity of a wavelength 14 to be analyzed. With such an arrangement and action, a microscopic sample introduction device can be incorporated into a system using an inexpensive monochromatic meter. |
