Abstract:For the purpose of decreasing the calibration uncertainty for aerosol diluter in traditional calibration method, and thus increasing results reliability, an aerosol diluter calibration method based on quantitative generator technology was proposed. The theoretical formula of aerosol quantitative generation technology was deducted firstly, an aerosol diluter calibration set-up with accurate and traceable chain was developed subsequently. And finally,the performance of the calibration device was verified and uncertainty analysis was conducted.The experimental results showed that the calibration device and method can achieve calibration of aerosol diluters within the dilution range of 1~300, with an uncertainty of 3.8%(k=2).
