Development of small CO2 gas measurements with AixMICADAS

After three years of tests and developments, the performances of the AixMICADAS facility have been established for small CO2 samples with a carbon mass inferior to 100 μg. The instrument shows very good stability and reliability when measuring small samples with its gas ion source. In this configuration, the precision is mainly limited by counting statistics and also the accuracy by contamination effects for the smallest samples (<20 μgC). A...
