Methods for calibration of the condensation particle counter (CPC) and characterization of the transfer function of the differential mobility analyzer (DMA), both of which have been developed at AIST, are discussed in this article. In the first part, the methodology for calibration of the detection efficiency of CPCs is explained. It will be used in the calibration service by AIST for CPCs and aerosol electrometers. The procedure is also proposed by us as part of a future ISO standard. In the second part, our method for evaluation of the transfer function of DMAs is discussed. It is based on the work by Martinsson <I>et al.</I> (<I>Aerosol Sci. Technol.</I>, <B>35</B>, 815 (2001)) which allows determination of the sizing resolution, particle losses, and their size dependence and has been improved by us. These calibration and characterization techniques for the CPC and DMA, which are the two crucial instruments for electrical mobility analysis, are expected to provide accuracy and reliability to size distribution measurements of aerosol nanoparticles.
