AB  - A four-stage personal diffusion battery (pDB) was designed and constructed to 
      measure submicron particle size distributions. The pDB consisted of a screen-type 
      diffusion battery, solenoid valve system, and electronic controller. A data 
      inversion spreadsheet was created to solve for the number median diameter (NMD), 
      geometric standard deviation (GSD), and particle number concentration of unimodal 
      aerosols using stage number concentrations from the pDB combined with a handheld 
      condensation particle counter (pDB+CPC). The inversion spreadsheet included 
      particle entry losses, theoretical penetrations across screens, the detection 
      efficiency of the CPC, and constraints so the spreadsheet solved to values within 
      the pDB range. Size distribution parameters (NMD, GSD, and number concentration) 
      measured with the pDB+CPC with inversion spreadsheet were within 25% of those 
      measured with a scanning mobility particle sizer (SMPS) for 5 of 12 polydisperse 
      combustion aerosols. For three tests conducted with propylene torch exhaust, the 
      pDB+CPC with inversion spreadsheet successfully identified that the NMD was 
      smaller than the constraint value of 16 nm. The ratio of the nanoparticle portion 
      of the aerosol compared to the reference (R(nano)) was calculated to determine 
      the ability of pDB+CPC with inversion spreadsheet to measure the nanoparticle 
      portion of the aerosols. The R(nano) ranged from 0.87 to 1.01 when the inversion 
      solved and from 0.06 to 2.01 when the inversion solved to a constraint. The pDB 
      combined with CPC has limited use as a personal monitor but combining the pDB 
      with a different detector would allow for the pDB to be used as a personal 
      monitor.
