固定污染源排气中非甲烷总烃(NMHC)的含量测定PQ预柱
固定污染源排气中非甲烷总烃(NMHC)的含量测定PQ预柱 详细信息：
名称：预柱
固定相：高分子小球
粒度：60-80目
规格：0.8m*1/8
型号：Porapak Q
应用：总烃，甲烷，非甲烷总烃的在线检测
依据：固定污染源废气 总烃、甲烷和非甲烷总烃的测定 气相色谱法（HJ 38-2017代替HJ/T 38―1999）
加强固定污染源中NMHC监测有益于人体健康,环境安全与生态平衡,使用气相色谱法配双柱双氢火焰离子检测NMHC含量效果较好.浩瀚色谱（山东）应用技术开发有限公司根据HJ/T38-1999《固定污染源排气中非甲烷总烃的测定气相色谱法》标准改造气象色谱仪,测试结果规定改造仪器合格,适用于固定污染源有组织排放和无组织排放的非甲烷总烃( NMHC)的检测,可投入使用. NMHC的检出量为4×10-2 ng,当色谱进样量为1.0 mL时,方法的检出浓度为0.2782 mg/m3,方法的定量测定浓度范围0.12~32 mg/m3.

PQ Pre-column for Determination of Non-Methane Total Hydrocarbons (NMHC) in Exhaust from Stationary Pollution Sources
PQ Pre-column for Determination of Non-Methane Total Hydrocarbons (NMHC) in Exhaust from Stationary Pollution Sources Details:
Name: Pre-column
Stationary phase: polymer beads
Granularity: 60-80 mesh
Specifications: 0.8m*1/8
Model: Porapak Q
Application: Online detection of total hydrocarbons, methane, and non-methane total hydrocarbons
Basis: Determination of total hydrocarbons, methane and non-methane total hydrocarbons in waste gas from stationary pollution sources-Gas chromatography (HJ 38-2017 replaces HJ/T 38-1999)
Strengthening the monitoring of NMHC in stationary pollution sources is beneficial to human health, environmental safety and ecological balance. The detection of NMHC content by gas chromatography with double-column double-hydrogen flame ionization is better. Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. according to HJ/T38- 1999 "Gas Chromatography Method for Determination of Non-Methane Total Hydrocarbons in Exhaust Gas from Stationary Pollution Sources" standard retrofits the gas chromatograph, and the test results stipulate that the retrofitted instrument is qualified, which is suitable for the determination of non-methane total hydrocarbons (NMHC) emitted by fixed pollution sources organized and unorganized. It can be put into use. The detection amount of NMHC is 4×10-2 ng, when the chromatographic injection volume is 1.0 mL, the detection concentration of the method is 0.2782 mg/m3, and the quantitative determination concentration range of the method is 0.12~32 mg /m3.
