Description:
The principle of the electrical aerosol analyzer method is reviewed and the diffusion battery method is described in detail. An appendix explains the basis of the calculations used. The diffusion battery method is complicated by counting losses of very small particles, inherent to condensation nuclei counters. A calibration of such counters is described, and results are introduced into the diffusion battery method; the mathematical details of this correction are discussed in a second appendix. Thus, the real size distribution of a polydisperse, ultrafine aerosol is obtained.
