Abstract

The invention relates to an aerosol on-line sampling device, an aerosol quantitative analysis system and a method, and aims to solve the technical problems that a conventional aerosol sampler and a quantitative analysis method are long in response time and quantitative analysis of individual particle aerosol cannot be performed. The sampling device disclosed by the invention comprises a collectingbottle, a sampling pipe, spray nozzles, a vacuum pump and liquid complementing equipment, wherein a liquid inlet and a liquid outlet are formed in the outer side of a bottle body of the collecting bottle in a tangential manner; and the liquid complementing equipment is connected with the liquid inlet to be used for complementing collecting liquid for the collecting bottle through the liquid inlet. During quantitative analysis, elements of which the analysis nature is similar to that of elements to be detected are selected as an internal standard element, and internal standard solutions are continuously changed into a detection and analysis instrument; then aerosol in environment is sampled through the sampling device, aerosol granules are collected into the collecting liquid, the collecting liquid and the internal standard solutions are mixed to form a mixed liquid at a tee, and then the mixed liquid enters the detection and analysis instrument for analysis; moreover, liquid complementing can be performed on the collecting liquid in the collecting bottle through the liquid complementing equipment.

Description

technical field [0001] The invention belongs to the intersecting field of environmental monitoring and chemical analysis, and in particular relates to an aerosol on-line sampling device, an aerosol quantitative analysis system and a method. Background technique [0002] Aerosols refer to solid or liquid particles that can be suspended in gas more stably, and play an important role in environmental climate, health medicine, economy, safety and other fields. At present, the prevention and control of air pollution is constantly advancing in depth, breadth, and intensity, and there is an urgent need for new environmental monitoring technologies and equipment. Compared with the aerosol offline monitoring method, the response time of the aerosol online monitoring method is greatly accelerated, and the concentration level and change trend of the aerosol can be obtained quickly, which can meet the needs of source analysis, process control and rapid response, so it is an aerosol moni...
