GISP2 Beryllium10 concentration, 719-2253 m ...

Melted water was collected from the outside of samples taken for cation and anion analysis by UNH. An aliquot was taken for anion analysis (chloride, nitrate, sulfate) and the remainder was weakly acidified with HNO3 to yield a final pH of about 2, Be, Cl and Al carriers were added. The Be (and Al a...

Description
Summary:Melted water was collected from the outside of samples taken for cation and anion analysis by UNH. An aliquot was taken for anion analysis (chloride, nitrate, sulfate) and the remainder was weakly acidified with HNO3 to yield a final pH of about 2, Be, Cl and Al carriers were added. The Be (and Al and Cl) were concentrated from melted ice using ion exchange resins. Be was eluted from the cation exchange column, precipitated as Be(OH)2 and ignited to BeO for accelerator mass spectrometry (AMS) measurement. AMS measurements at the Lawrence Livermore National Laboratory Center for Accelerator Mass Spectrometry (Davis et al., 1990). The 10Be (half-life =1.5x10^6 years) concentration was normalized to an ICN standard after carrier blank and boron background correction. ...
