Materials with known 11B/10B isotopic composition
IAEA-B-5, Basalt
Unit Size: 30 g
Price per Unit: 50 €
Date of Release: 2004
IAEA-B-5 is natural basalt, originating from the Etna Volcano eruption in 1998 and was prepared by the
Istituto di Geoscienze e Georisorse, Pisa, Italy. The material was ground to a grain size generally smaller
than 5 µm with a few grains up to 40 µm, mixed and homogenized [1]. The recommended values of the quality control
material are the results of the statistical evaluation of an interlaboratory comparison exercise [2].
