FIELD: physics.
SUBSTANCE: device for determining manganite concentration of rare-earth elements (MREE) consists of a light source - a mercury lamp, a light source power supply unit, a light rays photodetector, a photodetector power supply unit, a microvoltmeter for measuring the photodetector current. The device also includes a set of light filters which allows only the transmission of emission line of mercury lamps with a wavelength of 546 nm on the study sample. The concentration of the specific studied MREE is determined by the reflection coefficient value at 546 nm wavelength and the previously obtained dependence of the reflection coefficient on the manganite concentration of rare-earth elements.
EFFECT: possibility of measuring the manganite concentration of rare-earth metals.
