Extended Data Table 5 Results of the accumulation tests with air standard aliquots of 7.52 × 10−12 cc of 84Kr

  1. Each test consists of the accumulation of three air standard aliquots of 7.52 × 10−12 cc of 84Kr. The test results are compared with measurements of air aliquots of 7.52 × 10−12 cc (average of n = 16 analyses) and of 2.37 × 10−11 cc (average of n = 5 analyses) of 84Kr. The measured Kr isotopic ratios from the accumulation tests are similar to the ones for air standard aliquots of 7.52 × 10−12 cc and of 2.37 × 10−11 cc of 84Kr.
