Abstract

The invention relates to an aerosol online sampling device, an aerosol quantitative analysis system and a method. In order to solve the technical problems that the existing aerosol sampler and quantitative analysis method have a long response time and cannot carry out quantitative analysis of single particle aerosol, the sampling device of the present invention includes a collection bottle, a sampling tube, a nozzle, a vacuum pump and a liquid replacement device; A liquid inlet and a liquid outlet are arranged tangentially on the outer side of the bottle body; the liquid replenishment device is connected with the liquid inlet, and is used to replenish the collection liquid to the collection bottle through the liquid inlet. In quantitative analysis, select the element with similar analytical properties to the element to be measured as the internal standard element, and continuously pass the internal standard solution into the detection and analysis instrument; after that, use the sampling device to sample the aerosol in the environment, and the aerosol particles are collected. In the collection solution, the collection solution and the internal standard solution are mixed at the tee and then enter the detection and analysis instrument for analysis; at the same time, the collection solution in the collection bottle is replenished with liquid replacement 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...
