When a Picarro δ¹³C-CO₂ analyzer is coupled with an Automate FX sample preparation device (A0302), the system provides δ¹³C measurements of the dissolved inorganic carbon in water samples or δ¹³C in solid carbonate samples. The AutoMate Prep Device adds phosphoric acid to the samples to liberate CO₂, which flows to the Picarro for δ¹³C-CO₂ analysis.

The system is fully automated for the measurement of 45 samples.

The AutoMate Prep Device acidifies samples to convert carbonates or DIC in water to CO₂ gas. Evolved CO₂ gas is transferred from the AutoMate Prep Device to the Picarro Liaison interface and then to the Picarro WavelengthScanned Cavity Ring Down Spectroscopy CO₂ isotope analyzer for carbon isotopic determination.
