| Abstract: | A self-made droplet sampling device using simulated wind tunnel was developed based on the gas diffusion theory,and the optimum sampling parameters were investigated by acetylacepton fluorescence spectroscopy.The results showed that satisfactory sampling effect could be achieved with good sensitivity and reproducibility when the injection velocity was set as 0.1 mL/min,voltage for convection fan as 9 V,and a sample tube with inner diameter of 5 mm was applied. |
