Product details
The GSGC-5301 online gas chromatograph uses a patented technology that combines a dedicated chromatographic column combination, central cutting and blowback technology, and hydrogen flame ionization detector (FID) technology for the detection of methane, non methane total hydrocarbons, and benzene derivatives at the A Institute. The sample is kept at 180 ℃ throughout the entire process, filtered and collected to the quantitative ring. Then, the injection valve is switched and the sample is separated by entering the chromatographic column under the drive of the carrier gas. The total hydrocarbons in the first path are detected by the FID detector. The second oxygen and methane are separated from the PQ chromatographic column and enter the 5A chromatographic column. After switching the valve position, hydrocarbons are backflushed and methane is detected by the FID detector. The third sample of benzene, toluene, xylene, ethylbenzene, etc. is separated in the analysis column through the pre column and detected by the FID detector. After switching the valve position, the heavy hydrocarbon components are blown back and released.
Typical spectrogram
·The analysis method is consistent with the standard method and GC-FID detection is used;
·Full process high-temperature 180 ℃ heat tracing sample transmission and high-temperature FID detection to avoid high boiling point VOCsSAdsorption and condensation
·Continuous operation without maintenance design, automatic cycle operation upon startup, truly online analysis;
·The entire flow path is designed with insulation at 180 ℃, without water vapor condensation, to prevent component corrosion and degradation. It is suitable for high temperature/high humidity/corrosive working conditions,
·Non methane total hydrocarbons and components such as benzene, toluene, and xylene are simultaneously detected online.
