The certified value of the Lithium content (mg/kg) is determined using high-performance inductively coupled plasma optical emission spectrometry (HP-ICP-OES). All measurements are traced gravimetrically to an internationally accepted reference material from NIST (USA). The values obtained from titration and HP-ICP-OES were checked for agreement. The values must agree with each other in the range of their uncertainty.
