Precise Measurement of Carbon Concentration and Isotopic Ratios in Silicate Rocks by a High Sensitivity Elemental Analyzer Coupled with a Continuous Flow Isotope Mass Spectrometry
The precise and accurate analyses of minor carbon in silicate rocks can provide valuable insights into the origin of fluid and formation processes.TheElemental Analyzer-Isotope Ratio Mass Spectrometry(EA-IRMS)is a quick analytical method using small quantities of sample.In thisstudy,EA-IRMSis appliedtoanalyzecarbon isotopic composition of trace carbon in silicate rock.Based on a series of tests,the key analytical parameters are confirmed.The normalization procedure and reference materials selection are as f...
