haohan固定污染源废气中总烃测定岛津HH-THC-II填充柱2m*4mm

总烃通常指在测定条件下，能被氢火焰离子化检测器（FID）响应的气态有机化合物的总和。它包括了除甲烷以外的众多挥发性有机物（VOCs），但通常不包括甲烷。有时，测定结果会以“总烃（以碳计）”或“非甲烷总烃（NMHC）”的形式表示。

非甲烷总烃（NMHC） = 总烃（THC） - 甲烷（CH₄）
NMHC是更受关注的指标，因为它对光化学烟雾的形成贡献更大。

固定污染源中总烃的测定是一项技术性很强的工作，核心是 《HJ 38-2017》标准方法，浩瀚色谱（山东）应用技术开发有限公司:依托气相色谱-氢火焰离子化检测器（GC-FID） 技术。要获得准确可靠的数据，必须严格控制采样代表性、系统气密性、除湿效果和仪器校准等关键环节。*终目标是准确获取总烃（THC） 和非甲烷总烃（NMHC） 的浓度，为环境管理和企业达标排放提供科学依据。

Total hydrocarbons usually refer to the total amount of gaseous organic compounds that can be detected by a hydrogen flame ionization detector (FID) under the specified conditions. It includes numerous volatile organic compounds (VOCs) other than methane, but typically does not include methane. Sometimes, the measurement results are expressed in the form of "total hydrocarbons (calculated as carbon)" or "non methane total hydrocarbons (NMHC)".
Non methane total hydrocarbons (NMHC)=total hydrocarbons (THC) - methane (CH ₄)
NMHC is a more closely monitored indicator because it contributes more to the formation of photochemical smog.
The determination of total hydrocarbons in fixed pollution sources is a highly technical task, with the core being the "HJ 38-2017" standard method. Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. relies on gas chromatography hydrogen flame ionization detector (GC-FID) technology. To obtain accurate and reliable data, it is necessary to strictly control key aspects such as sampling representativeness, system airtightness, dehumidification effect, and instrument calibration. The ultimate goal is to accurately obtain the concentrations of total hydrocarbons (THC) and non methane total hydrocarbons (NMHC), providing scientific basis for environmental management and corporate emissions compliance.
