Analysis chromatograph for sulfides in petrochemical gases

Execution standards:

GB/T 28727-2012Gas analysis - Determination of sulfides - Flame photometric gas chromatography method.

Analysis chromatograph for sulfides in petrochemical gasesAnalysis components:

H2S、COSTotal sulfur, total organic sulfur, and other forms of sulfur (methyl mercaptan, methyl sulfide, ethyl mercaptan, carbon disulfide, ethyl sulfide, thiophene, dimethyl disulfide, methyl ethyl disulfide); This configuration can flexibly detect sulfur-containing components according to user requirements, including total sulfur, organic sulfur, etc.

Main features and advantages:

1. Adopting a fully inert analysis system, the minimum concentration detected can reach0.01ppm；

2. High column load and high degree of automation;

3. Flexible and versatile analysis process, optional packed column or capillary column analysis, durable and easy to maintain;

4. Rapid analysis of gases using blowback methodH2SHydrogen sulfide and total organic sulfur can determine the total sulfur content;

5. Suitable for any gas sample containing sulfides, with a separate organic sulfur analysis channel for detecting components such as methyl mercaptan, carbon disulfide, ethyl sulfide, thiophene, etc;

6. Set gas flow rate through anti control software（EPCSave all parameters of the analysis method, including type, external events, temperature, and detectors;

7. Fully electronic gas path controlEPCThe system,0.001psiThe control accuracy can provide better retention time and peak area precision, which can achieve better reproducibility and more consistent and reliable results,yield twice the result with half the effort.

8. Optional gas cut-off protection function, when the carrier gas pressure is lower than0.1MPaAt this time, the instrument automatically shuts down the main control circuit and enters standby mode to protect the detector and chromatographic column.

9. 7Inch color touch screen, human-machine interactive operation interface,GCThe host can provideRS232Communication port andLANENetwork port.
