摘要
为解决传统大气挥发性有机物检测误差大的问题,本研究基于气相色谱质谱联用设计一种新型大气挥发性有机物检测方法。其间通过提取大气挥发性有机物漫反射色谱质谱特征参数,基于气相色谱质谱联用计算大气挥发性有机物检出限,通过建立大气挥发性有机物检测矩阵,实现大气挥发性有机物检测。实例分析结果表明,设计检测方法的检测结果误差明显低于对照组,它能够解决传统大气挥发性有机物检测误差大的问题。
In order to solve the problem of large errors in the detection of traditional atmospheric volatile organic compounds,this study designs a new atmospheric volatile organic compound detection method based on gas chromatography-mass spectrometry.Meanwhile,by extracting the characteristic parameters of diffuse reflectance chromatographic mass spectrometry of atmospheric volatile organic compounds,the detection limit of atmospheric volatile organic compounds is calculated based on the combination of gas chromatography-mass spectrometry,and the detection of atmospheric volatile organic compounds is realized through the establishment of atmospheric volatile organic compounds detection matrix.The results of the case analysis show that the error of the detection result of the designed detection method is significantly lower than that of the control group,and it can solve the problem of large errors in the detection of traditional atmospheric volatile organic compounds.
