Analysis of unknown gaseous components

Using a gas chromatograph to analyze it, you can determine what type of exhaust gases are emitted by your company; even trace amounts of hydrogen sulfide and similar substances can cause an unpleasant odor.

Ammonia, nitrogen, COS, etc. generated in the production process aside from hydrogen sulfide…

The exhaust gases emitted by any device can be estimated based on information such as the process medium, operating conditions, and separation processes. I believe that the methods available for studying and analyzing the mechanisms of industrial processes are now quite mature. The original poster can definitely help by discussing with others the details of the equipment, the manufacturing process, as well as the raw materials and products, as this will facilitate getting accurate assistance. What you call the unknown is due to your possible lack of understanding of the changes in processes, raw materials, products, and their manufacturing processes. Please provide details on the specific manufacturing process, as well as information on raw materials, products, additives, catalysts, etc. I believe that with so many people here at Haichuanli, including myself, we can offer you some suggestions and guidance.

On the rooftop, LZ provided too little information, so it’s impossible to make a judgment. However, you can determine the possible components through specific techniques, and then select appropriate analysis methods for the particular project.

Due to technical confidentiality reasons, it’s not possible to disclose our manufacturing processes; we’re simply wondering if there is any way to determine the composition of unknown gases； However, thanks to everyone’s suggestions, we are also analyzing the possible components. But since this is a new process, we lack relevant experience, so we’re not very confident in this regard

Although your process department says that those exhaust gases you emit can’t just appear out of nowhere, right! Think about what your Hui would reply Then just buy some standard substances to perform chromatographic qualitative analysis, and that’s it!

Well, thank you all for such great suggestions. We’ll give them a try. Thank you everyone

If your exhaust doesn’t contain many organic isomers, it’s sufficient to have a third-party testing company conduct a GC-MS analysis; the mass spectrometer can help identify the components based on their molecular weight

Gas test tubes can be used to detect the approximate composition and concentration of gases. By specifically selecting the appropriate chromatography method, it is possible to reduce excessive gas content and thus prevent damage to the chromatography column.
