Abstract
The results of the first international inter-comparison of 10Be 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 10Be concentrations agree within their uncertainties for six out of seven samples with 10Be concentrations greater than 1 × 104 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 9Be 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.
