摘　　要：根据《环境空气挥发性有机物的应急测定便携式气相色谱质谱法》(HJ 1223—2021)的要求,分别对15种挥发性有机物的校准曲线、检出限、精密度和准确度等参数进行实验室方法验证。实验结果表明,低浓度和高浓度校准曲线响应因子相对标准偏差、检出限、精密度和准确度基本满足标准方法要求,该标准方法具有可操作性。According to the requirements of the portable gas chromatography-mass spectrometry method for emergency determination of volatile organic compounds in ambient air(HJ 1223—2021),laboratory method validation was conducted on the calibration curves,detection limits,precision,and accuracy parameters of 15 volatile organic compounds.The experimental results show that the relative standard deviation,detection limit,precision,and accuracy of the response factors of low and high concentration calibration curves basically meet the requirements of the standard method,and the standard method is operable.
