PROBLEM TO BE SOLVED: To provide a high-frequency inductively coupled plasma emission spectrometric analysis method of high analytical accuracy and high reliability for arsenic-containing solutions. SOLUTION: The high-frequency inductively coupled plasma emission spectrometric analysis method for arsenic-containing solution is a composition-analyzing method, where the concentration of arsenic in the arsenic-containing solution is measured in a photometric time that brings the measurement dispersion of arsenic to 0.025 mg/l or smaller. According to this method, high-accuracy and reliable analysis becomes possible. Furthermore, higher accuracy and reliability analysis becomes possible, by making a liquid with a pH of 6-8 pass through the measuring sample inlet part, through which the measuring sample is passed, of the high-frequency inductively coupled plasma emission spectrometric analyzer.
