The effective density and fractal dimension of soot particles from premixed flames and motor vehicle exhaust

A tandem differential mobility analyzer (DMA)—electrical low pressure impactor (ELPI)—is employed to measure the effective density, mass per unit mobility volume, of soot particles. These measurements reveal a sharp decline in soot effective density from ∼1.2 g/cm 3 at 30 nm to
