非甲烷总烃超过一定浓度,会对人体产生刺激作用,危害呼吸系统,还可能提高心血管疾病的风险。
在一定条件下经日光照射能产生光化学烟雾,形成细颗粒物等污染物,对空气质量造成负面影响。
非甲烷总烃成分复杂,含量低,要求监测仪器有高灵敏度和精度。一些仪器在低浓度检测时,易出现基线漂移、噪声干扰等问题,影响测量精度。
采样过程中,非甲烷总烃易被采样管路吸附或在富集解析过程中损失,影响测量准确性。
环境空气中存在多种干扰物质,如有机硫、胺、水汽等,会对非甲烷总烃的监测产生干扰,影响测量结果的准确性。
吸附技术是利用多孔性固体材料(吸附剂)的表面吸附力,将废气中的非甲烷总烃截留并富集,

Non methane total hydrocarbons exceeding a certain concentration can cause irritation to the human body, harm the respiratory system, and may also increase the risk of cardiovascular disease.
Under certain conditions, exposure to sunlight can produce photochemical smog, forming pollutants such as fine particles, which have a negative impact on air quality.
Non methane total hydrocarbons have complex composition and low content, requiring monitoring instruments to have high sensitivity and accuracy. Some instruments are prone to baseline drift, noise interference, and other issues during low concentration detection, which can affect measurement accuracy.
During the sampling process, non methane total hydrocarbons are easily adsorbed by the sampling pipeline or lost during the enrichment and analysis process, which affects the measurement accuracy.
There are various interfering substances in the ambient air, such as organic sulfur, amines, water vapor, etc., which can interfere with the monitoring of non methane total hydrocarbons and affect the accuracy of measurement results.
Adsorption technology utilizes the surface adsorption force of porous solid materials (adsorbents) to intercept and enrich non methane total hydrocarbons in exhaust gas. Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. developed the "Application of Non Methane Total Hydrocarbon Adsorption Tube in Shimadzu GC2014" to determine non methane total hydrocarbons in solid pollution source exhaust gas. The enrichment effect is good and has achieved good results on a thermal analyzer.
