The principle behind operating the Model 3082 Electrostatic Classifier with 
any DMA is based on the monotonic relationship between electrical 
mobility and particle size of single-charge particles. To ensure a fixed 
percentage of particles carrying one unit of charge, the particles are 
introduced to a bipolar charge in a Model 3077/3077A or a Model 3088 
Neutralizer where they undergo frequent collisions with ions of both 
positive and negative polarity. This process is known as bipolar charging or 
“neutralization.” As a result, an equilibrium charge state is obtained, with 
known percentages of particles carrying no charge, a single charge, or 
multiple charges of both positive and negative polarities. These aerosol 
particles are then classified with the differential mobility analyzer and can 
be measured by a Condensation Particle Counter or an Aerosol 
Electrometer. The mobility distribution, and hence size distribution, can be 
determined from the measurement. 

H i s t o r y  

Electrical mobility techniques have been used to measure the size 
distribution of aerosols since the work of Rohmann [1923]. The differential 
mobility analyzer (DMA) was developed and used initially for electrical 
mobility measurements of submicrometer particles [Hewitt, 1957]. 
 
Liu and Pui [1974] used the differential mobility analyzer with a bipolar 
charger to produce monodisperse aerosols of known size. Their design 
was used to develop the first commercial DMA, the TSI Model 3071 
Electrostatic Classifier. Not long after the development of the DMA, 
Knutson and Whitby [1975] incorporated the DMA into a particle-sizing 
system. The commercial system was known as the Model 3932 Differential 
Mobility Particle Sizer (DMPS). 
 
The interface hardware was developed by TSI Incorporated. Knutson 
[1976] developed a data inversion technique for obtaining the initial aerosol 
size distribution based on the measured particle mobility distribution. A 
data inversion technique si

milar to Knutson’s was used in the commercial 

DMPS/C data reduction. The data inversion technique is based on the 
work of Plomp, et al. [1982] and Hoppel [1978], and the data reduction 
technique was developed by Fissan et al. [1982]. The approximation of the 
bipolar charge distribution on submicrometer particles has been taken from 
the work of Wiedensohler [1986, 1987] and Wiedensohler and Fissan 
[1988].
