【 摘 要 】

The results of the first international inter-comparison of Be-10 analysis from quartz are presented. This inter-comparison includes the sample preparation starting from pre-purified quartz and AMS measurements at SUERC and ANU. Measured Be-10 concentrations agree within their uncertainties for six out of seven samples with Be-10 concentrations greater than 1 X 10(4) at/g quartz. This agreement and also the agreement of 10Be concentrations analysed from two aliquots of the same sample at SUERC indicate that addition of Be-9 carrier before (used at ANU) or after quartz dissolution (used at SUERC apart from one aliquot of one sample) should not result in substantially different results.
