Method for the continuous measurement of the mass of aerosol particles in gaseous samples and a device for the implementation of the method |
摘要 |
For a continuous measurement of the mass of absorbing particles in a gaseous sample, the sample is traversed by electromagnetic radiation of a wavelength greater than the mean radius of the particles. The difference in absorption for at least two frequencies is determined and appointed to the particle mass sought after.
