名稱：毛細管柱

規格：30m*0.53mm

型號：HH-THC-30

應用：環境空氣，非甲烷總烴，甲烷，總烴測定；固定污染源廢氣，甲烷，總烴，非甲烷總烴測定  氣相色譜法

滕州市浩瀚色譜儀器技術服務有限公司，根據非甲烷總烴排放標準、分析方法和實際監測情況,對非甲烷總烴定義、總烴峰型異常、氧峰干擾、方法檢出限測定和采樣容器選擇等方面存在的問題進行了探討。結果表明:氣態烴的衍生物屬于非甲烷總烴,烴的衍生物和色譜柱類型是導致總烴峰型異常的主要原因,使用除烴空氣作載氣可消除氧峰干擾,非甲烷總烴為差值結果,應按照EPA SW-846標準測定檢出限,PVF氣袋本底低、氣密性和化學惰性好,是zui的非甲烷總烴采樣容器。

Improved non-methane total hydrocarbon determination method
Improve non-methane total hydrocarbon determination method Details:

Name: Capillary Column

Specification: 30m*0.53mm

Model: HH-THC-30

Application: Determination of ambient air, non-methane total hydrocarbons, methane, total hydrocarbons; determination of stationary source waste gas, methane, total hydrocarbons, non-methane total hydrocarbons, gas chromatography



Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd., based on non-methane total hydrocarbon emission standards, analysis methods and actual monitoring conditions, defines non-methane total hydrocarbons, abnormal peak patterns of total hydrocarbons, oxygen peak interference, method detection limit determination and sampling container The problems in selection and other aspects were discussed. The results show that the derivatives of gaseous hydrocarbons belong to non-methane total hydrocarbons. Hydrocarbon derivatives and column types are the main reasons for the abnormal peak pattern of total hydrocarbons. Using hydrocarbon-removing air as a carrier gas can eliminate the interference of oxygen peaks. For the difference result, the detection limit should be determined according to the EPA SW-846 standard. The PVF air bag has a low background, good air tightness and chemical inertness, and is the best non-methane total hydrocarbon sampling container.
