SIMULTANEOUS CO2 AND H2O ISOTOPES
Aerodyne’s simultaneous carbon dioxide and water vapor isotope monitor is a dual laser instrument which provides the excellent sensitivity and time response (0.1 seconds) of our standard CO2 isotope monitor but also measures the isotopic abundances of H218O and HOD.
The measurement precisions for a one second measurement at typical ambient atmospheric mixing ratios of CO2 and water vapor are:
|H2O||HOD/H2O||0.3 per mil|
|H218O/H2O||0.1 per mil|
|CO2||13CO2/CO2||0.1 per mil|
|CO18O/CO2||0.1 per mil|
