Enzymatically catalyzed CO2‐H2O equilibration for oxygen isotope analyses of aqueous samples
Abstract
RATIONALE: The classic CO2 -H2 O equilibration method is a very popular technique for the measurement of the oxygen isotope composition of aqueous samples in stable isotope geochemistry. This study examined whether enzymatically controlled CO2 -H2 O equilibration by carbonic anhydrase (CA) could reduce the time for oxygen isotope equilibrium between CO2 and H2 O at 25°C.
METHODS: Four types of aqueous samples containing CA were equilibrated …
