Atomic absorption spectrometric determination of indium

The determination of indium in heavily doped gallium arsenide (0.2–1.2 mg g−1 In), by both electrothermal and flame AAS is reported. The sample is first decomposed with nitric acid and the diluted solution is atomized by employing the more convenient technique. The conventional air-acetylene flame is used for samples containing at least 1 mg g−1 indium. For lower concentrations the
