英文摘要
A new mid-infrared laser spectrometer designed to measure the CO2 isotopologues of carbonates including the doubly substituted CO2 isotopologue has developed. This instrument has some advantage compared with mass spectrometer: 1) ionization is not needed, 2) no overlap with the absorption area of water, 3) high detection limit (ppt level). This new approach to the analysis of clumped isotopologues in carbonates dramatically expands the areas in which they can be applied.
