Abstract
Quality assurance and control (QA/QC) are sacrosanct for accelerator mass spectrometry (AMS) sample preparation laboratories. However, quantitative data necessary to assess QA/QC is rarely published for cosmogenic nuclide sample preparation laboratories around the world. Here, we compile and report QA/QC data for the first 5 years of Be-10 sample preparation operations in the CosmIC laboratory at Imperial College London, United Kingdom. Our QA/QC data include: 1) inductively coupled plasma - optical emission spectroscopy (ICP-OES) assay data for mineral purity, carrier concentration, beryllium yield, and beryllium purity; 2) AMS data for ion beam current, carrier blanks, laboratory process blanks, and measured isotope ratio versus precision; and 3) nuclide concentration data for replicate samples. These results serve to verify and benchmark our current Be-10 sample preparation methods and data quality. In turn, our QA/QC data set the bar for future development and improvements in the CosmIC laboratory and other cosmogenic isotope sample preparation laboratories globally.
