Standard Reference Material (SRM<sup>®</sup>) 699 Alumina (Reduction Grade) was digested in HCl at 240 °C inside Carius tubes. Beryllium was measured with inductively coupled plasma optical emission spectrometry at the 313.107 nm line and quantified to be 2.90 ± 0.24 μg g<sup>â 1</sup> by the method of standard addition. The uncertainty of the measurement was evaluated by taking into account the often-neglected contribution from the correlation between the intercept and the slope of the regression curve.
