Abstract The calibration method of gas-phase molecular absorption spectrometer was established. Combining with
the working principle and structure of the instrument， performance evaluation parameters including the detection limit，
measuring linearity，quantitative reproducibility were proposed. Measurement uncertainty of its detection limits by using
the state standard solution was evaluated，which could unify the calibration method to effectively ensure the accuracy and
traceability of the measurement data. Some guidance on the measurement of calibration and formulation of verification
regulation for metrological verification institutions were provided.
