This standard specifies a method for the determination of selenium and tellurium in silver by Inductance coupled plasma atomic emission spectroscopy (AES), suitable for the determination of selenium content between 0.0002% and 0.010% and tellurium content between 0.0002% and 0.010%. The standard separates the matrix silver by settling in an acidic medium and measures the emission intensity of selenium and tellurium at specific wavelengths. The method provides an accurate means of trace element analysis and is suitable for quality control of trace elements in silver and its alloys.
