Product Details

The principle of the method specified is dissolving a test portion in acid, aspiring the test solution into a nitrous oxide-acetylene flame of an atomic absorption spectrometer, measuring the absorbance of the resonance line energy from the spectrum of vanadium and comparison with that of calibration solutions at a wavelength of 318,4 nm. The method may be used to determine vanadium contents in the range of 0,05 % (m/m) to 1 % (m/m).
