On the performance of an on-line time-of-flight mass spectrometer for aerosols

Correction of the effect of particle shape on the size distribution measured with a laser diffraction instrument

Dust explosions in spherical vessels: Prediction of the pressure evolution and determination of the burning velocity and flame thickness

A well known limitation of the ’cube-root-law’ is that it becomes invalid when the flame thickness is significant with respect to the vessel radius. In the literature flame thicknesses in dust-air mixtures ranging from 15 to 80 centimeters have been reported [1], which exceed the radii of the 20-1itre sphere and the 1 m3 vessel. Therefore we...

The online chemical analysis of single particles using aerosol beams and time of flight mass spectroscopy

This paper describes an on-line instrument, capable of measuring the size and chemical composition of single aerosol particles. Possible applications include monitoring aerosol reactors and studying atmospheric chemistry. The main conclusion is that a working prototype has been built and tested. It uses a three stage vacuum system to generate an...
