隨著現代工業的日益發展,大氣污染也日漸加劇。甲醇是現代石油化工行業常用原料之一,在生產過程中,不可避免地會釋放到空氣中,甲醇屬于有毒有害、易燃易爆的物質。非甲烷總烴(NMHC)通常是指除甲烷以外的所有可揮發的碳氫化合物。大氣中的NMHC超過一定濃度時,除直接損害人體健。

滕州市浩瀚色譜儀器技術服務有限公司，采用單一進樣口六通閥進樣,Porapak Q柱和空柱兩根填充柱及一個FID檢測器的氣相色譜法測定無組織大氣中甲烷、總烴和非甲烷總烴,測定結果均符合大氣污染物綜合排放標準中無組織排放監控標準要求。方法低檢出濃度分別為甲烷0.04 mg/m3,總烴0.04 mg/m3,非甲烷總烴0.06 mg/m3,甲醇2 mg/m3,且能保持良好的重復性,相對標準偏差均小于2%,滿足檢測的要求。該方法操作簡單、靈敏且分離度好,具有較好的重現性和的準確度。

With the development of modern industry, air pollution is also increasing. Methanol is one of the commonly used raw materials in the modern petrochemical industry. In the production process, it is inevitably released into the air. Methanol is a toxic, harmful, flammable and explosive substance. Non-methane total hydrocarbons (NMHC) generally refer to all volatile hydrocarbons other than methane. When the NMHC in the atmosphere exceeds a certain concentration, it directly damages the human health.

Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. uses a single inlet six-port valve injection, Porapak Q column and two empty packed columns and a FID detector for gas chromatography to determine methane, total hydrocarbons and unorganized atmosphere. Non-methane total hydrocarbons, the determination results are in line with the requirements of unorganized emission monitoring standards in the comprehensive emission standards for atmospheric pollutants. The minimum detectable concentrations were 0.04 mg/m3 for methane, 0.04 mg/m3 for total hydrocarbons, 0.06 mg/m3 for non-methane, and 2 mg/m3 for methanol, and maintained good repeatability. The relative standard deviations were less than 2%. , to meet the requirements of testing. The method is simple, sensitive and has good resolution, and has good reproducibility and reliable accuracy.
