METHOD AND APPARATUS FOR ANALYZING VAPORIZED METAL

摘要

A laser beam is passed through a vaporized metal layer, and the change in its luminous flux density is measured to determine the concentration of the element under analysis included in the vaporized metal. The wavelength of the laser beam is adjusted such that it is 0.001 to 0.03 nm off the center of the absorption wavelength of the element under analysis. The range of concentration measurement can be expanded.
