Diffusion deposition loss was only 3.5% for 15 nm particles. When Pod was reduced to 5.4 Torr, nanoparticle diffusion loss was still low however inertial impaction loss was increased to 50%, which mainly occurs at the tube wall downstream of the orifice.

For example, increasing inner diameter from 6.2 mm to 25 mm, particle loss was reduced to zero.
