In-situ extraction type laser ammonia escape analysis system

The invention relates to an in-situ extraction type laser ammonia escape analysis system which comprises a detection module mounted at a gas collection point and used for collecting gas parameters and transmitting the gas parameters to a control module for processing through a signal cable; the detection module comprises a high-temperature chamber, a gas detection device arranged in the high-temperature chamber and a sampler, the outer side wall of the high-temperature chamber is provided with an insertion pipe used for being inserted into a gas collection point, and the sampler comprises a sampling rod embedded in the insertion pipe; the control module is used for receiving and processing the gas parameters sent by the detection module; structures, needing heat tracing devices, of a traditional ammonia escape device are all arranged in the high-temperature chamber, equivalently, a sampler and a detection unit are integrated together, so that on one hand, a complex heat tracing structure can be omitted, the m
