Technical Field

[0001] This utility model relates to the field of gas sampling and analysis, and specifically to a gas sampling and analysis device. Background Technology

[0002] With the energy structure shifting towards low-carbon development, the market demand for biogas is growing. Biogas typically contains components such as methane, carbon dioxide, hydrogen sulfide, nitrogen, and water, and its value differs significantly from that of traditional natural gas. Its transportation process requires a rigorous and reliable certification system as support. Therefore, it is necessary to monitor the composition of biogas, and gas analyzers are commonly used equipment for analyzing the composition of biogas.

[0003] While existing gas analyzers can generate biomass natural gas monitoring data, their technical focus is usually on improving analysis accuracy, stability, and response speed. The generated data does not have a unique and inseparable binding relationship with a specific monitoring location or specific equipment, which means that monitoring equipment can be easily transferred to another gas source location, making the monitoring data untraceable and susceptible to data falsification.
