岛津GC2010总烃柱HH-THC-II测定固定污染源废气
岛津GC2010总烃柱HH-THC-II测定固定污染源废气 详细信息：
《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）
这个标准取代了旧的HJ/T 38-1999，是MU前进行固定污染源总烃测定的法定依据。
该方法明确规定了使用GC-FID，通过双柱（总烃柱和甲烷柱）、单FID检测器，或双FID检测器的系统进行测定。
浩瀚色谱（山东）应用技术开发有限公司,j进行实验室分析：
进样：将采集的样品气通过进样阀或注射器注入气相色谱仪。
分离与检测：样品shou先进入色谱系统。
一路通过总烃柱，直接进入FID，得到总烃（THC）的峰。
另一路通过甲烷柱，将甲烷与其他烃类分离，然后依次进入FID，得到甲烷（CH?）峰和非甲烷总烃（NMHC）的加和峰。
定量：通过比较样品峰的响应值与校准曲线的响应值，计算出样品中总烃和甲烷的浓度。
结果计算与报告：
根据测得的THC和CH?浓度，计算NMHC浓度：NMHC = THC - CH?。
结果通常以“毫克/立方米（mg/m3）”表示，并注明是标准状态下的干基浓度。

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. conducted laboratory analysis:
Injection: Inject the collected sample gas into the gas chromatograph through an injection valve or syringe.
Separation and detection: The sample first enters the chromatographic system.
Passing through the total hydrocarbon column, it directly enters the FID and obtains the peak of total hydrocarbons (THC).
The other route passes through a methane column to separate methane from other hydrocarbons, and then sequentially enters the FID to obtain the methane (CH ?) peak and the sum peak of non methane total hydrocarbons (NMHC).
Quantification: Calculate the concentration of total hydrocarbons and methane in the sample by comparing the response values of the sample peaks with the response values of the calibration curve.
Result calculation and reporting:
Calculate the NMHC concentration based on the measured THC and CH ? concentrations: NMHC=THC - CH ?.
The results are usually expressed in milligrams per cubic meter (mg/m 3) and are indicated as the dry basis concentration under standard conditions.
