Overview
The Purui CMS-6000 non methane total hydrocarbon/benzene series online gas chromatograph adopts a three valve, four column, FID configuration, and high-temperature heating throughout the process. The sample is quantified by a quantitative loop, injected by three valves, separated by four columns, and detected by a hydrogen flame ionization detector (dual FID). The first FID measures the concentration of total hydrocarbons (THC) and methane (CH4) in the sample, the concentration of non methane total hydrocarbons (NMHC) is calculated by subtraction, and the second FID measures the concentration of each component of the benzene series in the sample. Suitable for monitoring the content of non methane total hydrocarbons and benzene, toluene, ethylbenzene, xylene, trimethylbenzene, etc. in pollution sources.

Product Introduction
PureCMS-6000Non methane total hydrocarbons/Benzene series online gas chromatograph, using three valves, four columnsFIDEquipped with high temperature tracing throughout the process, the sample is quantified by a quantitative loop, injected with three valves, and separated by four columns before being detected by a hydrogen flame ionization detector (dual)FID）Testing, beforeFIDDetermine the total hydrocarbons in the sample（THC）And methane（CH4）Concentration, non methane total hydrocarbons（NMHC）The concentration is calculated by subtraction, and thenFIDMeasure the concentration of each component of the benzene series in the sample. Suitable for monitoring the content of non methane total hydrocarbons and benzene, toluene, ethylbenzene, xylene, trimethylbenzene, etc. in pollution sources.
Product Features:
Stable and secure operation, achieving unmanned operation and low maintenance costs:
Self protection function, when the gas supply is insufficient, the flame will automatically extinguish and the hydrogen and air flow will be turned off to prevent leakage.
Automatic ignition, automatically ignites and runs after startup, restoration of gas supply, or unexpected power outage.
instrumentGood repeatability in qualitative and quantitative analysis（≤1%）Low detection limit:
uFID detection limit as low as1.8×10-12 g/s.
uHigh stability temperature control system:0.01 ℃。
uHigh precision electronic pressure control unitEPC（0.001psi）Realize temperature and pressure compensation.
At the bottomLow maintenance and long service life: the proportion of imported parts is as high as40%.
At the bottomThe software is easy to operate and maintain,SINZEN supports customized services.
