摘要： Distributed non-charged particles having a desired particle diameter are introduced into a chamber. A photoionizer in which a soft X-ray power is adjustable is attached to the chamber, to charge the particles within the chamber. The power level of the soft X-ray is adjusted by a controller so as to produce singly charged particles. The charged particles are then introduced into a differential mobility analyzer for classification, thus producing monodisperse standard particles having particle diameter of 0.1 to 1.0 μm.
