PROBLEM TO BE SOLVED: To provide an automatic elementary analysis technique in which the blocking of piping and interference with analysis accuracy hardly occur by efficiently removing high-salts components in high-saline water. SOLUTION: The device for automatically analyzing elements in high-salts water includes a means (A) for performing pH adjustment on a high-salts aqueous solution, a means (B) for preparing a solution by performing a precipitating operation, separating a precipitate from the aqueous solution by filtering, washing the precipitate, separating the precipitate from a washing water, and dissolving the precipitate, and a means (C) for performing elementary analysis through the use of the solution. In the device for automatically analyzing elements in high-salts water, the operations of pH adjustment, precipitation, filtering, washing, and dissolution and liquid feeding among the means are automatically performed.
