| Abstract: | An aerosol time-of-flight mass spectrometer that can be used for real-time measurement of chemical compositions of individual aerosol particles had been designed and manufactured in our laboratory. Two kinds of combustion aerosol particles had been measured using it. Experimental results showed that the individual aerosol particles and real-time measurement could be performed by this instrument. This unique capability is impossible for those off-line methods such as gas chromatography and chemical method. |
