The limit of detection for **1**0Be by accelerator mass spectrometry has been lowered to a few million atoms by the installation of a Wien filter which screens out co-transmitted **9Be. Analyses of six Central American basalts gave **1**0Be contents ranging from 1 multiplied by 10**6 to 60 multiplied by 10**6 atom/g. The sample richest in **1**0Be has been contaminated by sediments. The other samples have **1**0Be contents in the range reported in the literature by Brown and co-workers.
