Product DescriptionAfter the air sample is pumped into the unique collection and separation device, the gaseous pollutants are absorbed by the annular wet diffusion tube due to the extremely fast diffusion rate. The aerosol penetrates through under the inertial action and is captured by the aerosol collection device. After the atmospheric gaseous and air soluble components are converted into solutions, they are alternately transported to the anion and cation ion chromatographs for comprehensive analysis of ion components, and the whole process is fully automatic.
Features
The wet annular diffusion tube can separate gas samples from aerosol samples with a separation efficiency of 98%;
The results show that the aerosol sample can be effectively collected by the aerosol long chamber and the aerosol collector, and the capture efficiency is as high as 99%;
The time resolution was 30 min (the gaseous / aerosol pollutants were collected for 15 min, and the samples were analyzed alternately);
It can be used for real-time analysis of gaseous pollutants and water-soluble components of PM2.5;
It has the ability of continuous sampling for a long time to meet the requirements of on-line monitoring;
Domestic ion chromatography or Diane imported ion chromatography can be selected.
Scope Of Application
The system can be used to measure water-soluble F -, Cl -, no 2 -, no 3 -, so 4 2 -, Na +, NH 4 +, K +, Mg 2 +, Ca 2 + and gaseous HF, HCl, HONO, HNO 3, so 2 and NH 3 in the atmosphere. It has a wide range of applications. It can monitor the concentration of relevant inorganic substances in the atmosphere and aerosol. Combined with meteorological data, it analyzes the causes of haze, explores the formation process and mechanism of haze, and provides scientific basis for control countermeasures.
The system can be applied to routine monitoring of water-soluble components of PM2.5 by environmental monitoring departments, comprehensive monitoring and monitoring of regional atmospheric environment by atmospheric super stations, and in-depth scientific research by scientific research departments such as universities and research institutes.
