Determination of microamount of silicon in steel by inductively coupled plasma-atomic emission spectrometry

Based on reviewing references and wavelength tables, experimental investigation of Si lines for the determination of Si in steel is reported. Calibration was made under conditions of matrix match and blank correction. Limit of detection is 6 x 10(-4) % for Si 212.412 nm and Si 251.612 nm and is two orders of magnitude better than the current national standard methods.
