GC-7990F 便携式非甲烷总烃气相色谱仪的详细资料

便携式非甲烷总烃气相色谱仪
便携式非甲烷总烃气相色谱仪 详细信息：

GC-7990F便携式非甲烷总烃气相色谱仪采用氢火焰检测器FID，可测量环境空气及固定污染源废气中的总烃和甲烷，可自动连续取样，连续监测，响应速度快。取样系统与分析系统全程保持在受控的高温状态，有效防止样品冷凝或损失，实现总烃/甲烷/非甲烷总烃的监测。

依据：
GB/T 16157-1996 固定污染源排气中颗粒物测定与气态污染物采样方法
HJ 1012-2018  环境空气和废气总烃、甲烷和非甲烷总烃便携式监测仪技术要求和检测方法
DB 11/T 1367  固定污染源废气甲烷/总烃/非甲烷总烃的测定便携式氢火焰离子化检测器法


样品导入便携式非甲烷总烃分析仪后，应能分别同时定量注入总烃检测单元（FID）和甲烷检测单元（甲烷检测单元通过催化剂能够将除甲烷以外的其他有机化合物全部氧化为二氧化碳和水，FID检测甲烷），同时测定总烃和甲烷的含量，两者之差即为非甲烷总烃的含量。

1.高度集成设计，便携方便
2.使用方便，操作简单
3.自动化程序高，软件功能强大
4.测量准确，有保障
5.全面的质控功能

Portable non-methane total hydrocarbon gas chromatograph
Portable non-methane total hydrocarbon gas chromatograph Details:

The GC-7990F portable non-methane total hydrocarbon gas chromatograph adopts the hydrogen flame detector FID, which can measure the total hydrocarbon and methane in the ambient air and fixed pollution source exhaust gas. It can automatically and continuously sample, continuously monitor, and has a fast response speed. The sampling system and the analysis system are kept in a controlled high temperature state throughout the process, effectively preventing sample condensation or loss, and realizing the monitoring of total hydrocarbons/methane/non-methane total hydrocarbons.

in accordance with:
GB/T 16157-1996 Determination of particulate matter in exhaust gas from stationary sources and sampling method for gaseous pollutants
HJ 1012-2018 Ambient air and exhaust gas total hydrocarbon, methane and non-methane total hydrocarbon portable monitor technical requirements and testing methods
DB 11/T 1367 Determination of fixed source exhaust gas methane/total hydrocarbons/non-methane total hydrocarbons portable hydrogen flame ionization detector method


After the sample is imported into the portable non-methane total hydrocarbon analyzer, it should be able to be quantitatively injected into the total hydrocarbon detection unit (FID) and the methane detection unit at the same time (the methane detection unit can oxidize all other organic compounds except methane into carbon dioxide and water through a catalyst. FID detects methane), and simultaneously determines the content of total hydrocarbons and methane. The difference between the two is the content of non-methane total hydrocarbons.

1. Highly integrated design, portable and convenient
2. Easy to use and simple to operate
3. High automation program, powerful software
4. The measurement is accurate and guaranteed
5. Comprehensive quality control function
