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.
