Claim One:
1. A nanoparticle measurement system comprising: a nanoparticle charger apparatus configured to receive a nanoparticle laden laminar flow, the charger apparatus including a preconditioner device having a saturator configured to introduce a working fluid to the nanoparticle laden flow and including a condenser coupled thereto configured to grow the particles using the working fluid comprised of a fluid having a high surface tension and a low vapor pressure so as to increase particle charge probabilities of the nanoparticles and achieve a low multiple charge probability of the particles, wherein a temperature within the saturator is 40° C. to 80° C. and a temperature within the condenser is 5° C. to 25° C., the charger apparatus further configured to charge the grown particles to obtain known charge fractions according to a Fuchs charge distribution before drying the particles to remove the working fluid; a differential mobility analyzer (DMA) operatively coupled to said nanoparticle charger apparatus and adapted to receive and separate the charged nanoparticles, wherein a higher charge probability increases throughput in the DMA; and an aerosol detector device operatively coupled to the mobility analyzer and adapted to conduct particle monitoring, wherein the low multiple charge probability of the particles improves monodispersity for size distribution measurements.
