ABSTRACT:
An apparatus for determining concentrations of mineral elements comprising an improved spectrometer wherein the spectrometer functions to diffract the light to be measured by means of a rotary grating and to determine the strength of light by using a single PM tube and further detects the wavelength of the diffracted light, by using a laser beam generator, reflective mirrors, photo diodes so as to analyze the composition and the concentration of mineral elements.
