摘要
An instrument for measuring the concentration of water isotopes in a gas sample loaded with water vapor, includes an analyzer; a vaporizer including a circuit that connects to the analyzer to transmit a vaporized calibration liquid to the analyzer and an output circuit for discharging the overflow of the vaporized calibration liquid, the output circuit arranged such that the overflow is discharged without passing through the analyzer and a purge circuit connected to the input of the vaporizer for sucking said vaporized purge fluid through the vaporizer during a purge operation, the purge circuit arranged such that the vaporized purge fluid does not pass through the analyzer; a selector for selectively establishing a first state establishing the circulation of the calibration liquid through the connection circuit and the circulation of the overflow through the output circuit and a second state establishing the circulation of the purge liquid through the purge circuit.
