1results about How to "Uniform characteristics" patented technology

The application relates to the technical field of performance evaluation of a biological aerosol sampler, and provides a biological aerosol sampler performance evaluation method, which comprises the following steps: environment construction: adjusting and maintaining the temperature, humidity, air pressure and air cleanliness in a calibration cabin to a preset target range; aerosol generation and homogenization: generating standard aerosols containing a target tracer in the calibration cabin, and mixing the air in the cabin to form a test aerosol environment with uniform spatial concentration distribution in a sampling area; dynamic sampling: making the detected sampler and a comparative sampler sample at multiple different spatial points in the calibration cabin; data comparison and analysis: performing performance calibration on the detected sampler according to the sampling data of the detected sampler and the comparative sampler. The environment conditions highly close to actual application scenarios are constructed, and the comprehensive performance of the biological aerosol sampler can be scientifically, systematically and quantitatively evaluated and calibrated.
