Description

The isotopic reference material ERM-AE142 is a solution of natural Pb in nitric acid (1 mol/L) with a Pb mass fraction of 100 mg/kg. Approximately 20 mL of this solution each is filled in PFA bottles. This material is designed for verification and validation of all procedures (e.g. TIMS, ICPMS) being used for the determination of Pb isotope amount ratios.
