The principle of the method specified is dissolution of a test portion in nitric acid, measurement of the absorption of the resonance line energy from the spectrum of indium in the test solution at a wavelength of 325,6 nm by an atomic absorption spectrometer fitted with a graphite furnace electrothermal atomizer, calibration by the standard additions method described in ISO 11438-1. Applies to indium contents in the range of 0,5 g/t to 2,5 g/t in ferronickel.
