Materials with known 11B/10B isotopic composition
IAEA-B-2, Groundwater
Unit Size: 50 ml
Price per Unit: 50 €
Date of Release: 2004
IAEA-B-2 is a groundwater sample collected from an alluvial aquifer in the lower basin of the Cecina River, Italy.
After filtration, water samples were acidified with boron free HCl and distributed into polyethylene bottles.
The material was prepared by the Istituto di Geoscienze e Georisorse, Pisa, Italy [1]. The recommended values of the
quality control material are the results of the statistical evaluation of an interlaboratory comparison exercise [2].
