Abstract: Abstract:The precision of isotopic analysis of trace CO2 samples at 10-100 IJllevel using a modern isotopic ratio mass spectrometer was investigated in this study. Results show that it varies considerably over different ranges of CO2 analyzed and no simple correlation can be observed. It thus suggests that isotopic analysis of trace CO2 samples is better performed with an optimal range of CO2 in order to ensure high quality data. Since analyzing the carbon and oxygen isotopic compositions of extraordinarily low yield of CO2 from biogenic carbonate samples has become a routine task in studying the high-resolution marine time-series records, results from this study shall shed light upon paleotemperature estimates and the associated paleoceanographic research.
