Abstract

The invention discloses a multi-channel air sampling device and method. The multi-channel air sampling device comprises a flow divider, a plurality of sampling components, a control module and a vacuum pump, wherein the flow divider comprises a gas inlet nozzle and a plurality of gas outlet nozzles, the number of the gas outlet nozzles of the flow divider is greater than or equal to that of the sampling components, the sampling component comprises a gas inlet nozzle and a gas outlet nozzle, the gas inlet nozzle of the flow divider is connected with external air through a gas inlet pipe, one gas outlet nozzle of the flow divider is connected with one gas inlet nozzle of the sampling component, the gas outlet nozzle of the sampling componentis connected with the control module, and the control module is connected with the vacuum pump so as to control the specified sampling componentto carry out collection or stop collection. According to the invention, atmospheric particulate samples or volatile organic gases in different particle size ranges can be collected for multiple times through remote control, and the sampling requirement of the unmanned aerial vehicle is met.

Description

Technical field [0001] The present invention relates to the field of air sampling, particularly a multi-channel air sampling apparatus and method. Background technique [0002] Restrictions on the monitoring means of atmospheric environment, observations and research of the spatial distribution characteristics of atmospheric pollutants in the boundary layer have deleted. In recent years, the emergence of drone atmospheric observation platforms solves the problem of monitoring blind spots within boundary layers, and combines drone and micro-sensors to perform three-dimensional stereoscopic observations for atmospheric boundary layers. However, there are currently mostly to use drones to conduct atmospheric pollutants to determine the concentration of pollutants and cannot be analyzed for subsequent laboratory. There is less research on the morphology and chemical composition of atmospheric particulate matter, mainly due to the limitations of sampling tools. Most of the existing pa...
