[Examination of spectral interference in ICP-atomic emission spectrometry and metal analysis on commercially available natural mineral water].
To investigate the spectral interference on ICP-atomic emission spectrometer (AES), the concentrations of 41 elements were measured when 42 standard solutions (1000 ppm) of a single element were introduced. Interference over 10 ppm was observed in 16 couples of elements out of 1681 examined and over 2 ppm in 54 couples. The concentrations of six elements (Ca, Mg, Na, S, Si, Sr) in 10 kinds of commercially available natural mineral water were determined simultaneously with the ICP-AES.
