浩瀚色谱采用固定污染源非甲烷总烃在线监测设备与实验室气相色谱及便携式气相色谱进行数据分析，研究监测数据之间的差异。结果表明，便携式非甲烷总烃气相色谱仪测定的数据与在线连续监测设备测定数据基本一致，满足检测要求。而实验室气相色谱检测得到的手工数据容易受到外界因素的干扰，导致结果偏离较大，波动剧烈。因此，在线监测设备的监测结果较为准确，分析速度快，可连续、实时监测固定污染源气体中的非甲烷总烃的含量，从而对固定污染源中VOCs的排放进行有效监管。

　　Haohan Chromatography uses fixed pollution source non methane total hydrocarbon online monitoring equipment, laboratory gas chromatography, and portable gas chromatography for data analysis to study the differences between monitoring data. The results show that the data measured by the portable non methane total hydrocarbon gas chromatograph is basically consistent with the data measured by online continuous monitoring equipment, meeting the detection requirements. The manual data obtained from laboratory gas chromatography detection is easily affected by external factors, resulting in significant deviation and drastic fluctuations in the results. Therefore, the monitoring results of online monitoring equipment are relatively accurate, with fast analysis speed, and can continuously and real-time monitor the content of non methane total hydrocarbons in fixed pollution source gases, thereby effectively regulating the emission of VOCs in fixed pollution sources.
