High-precision argentometric titration was used for the determination of the bromide content in a Lithium bromide stock solution. 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.

Application

This product is suitable for the Metrohm MARGA instruments as internal standard solution.
