The concentration of an additional element, 75–100 mg/L, was selected based on the constancy of the analytical signals of analytes and the magnesium ratio Mg(II)/Mg(I). This concentration is insufficient for a significant change in temperature or electron density; that is, the added element is not a spectral buffer. The procedure was applied to the analysis of pore waters of bottom sediments of Lake Bolshoy Bagan (alkaline type of mineralization); the accuracy of the analysis was confirmed by the spiking method.",
