Venacontra Porous Tube Diluter (VC-PTD) is designed to be used in an aerosol sampling with wide range of dilution ratios and minimal losses. The VC-PTD offers excellent diluting properties when gentle and reliable sampling is needed. The Venacontra Porous Tube Diluters are commonly used in aerosol research such as combustion studies, vehicle emission studies and a nanoparticle synthesis. This diluter type allows a wide range of dilution ratios, from 2 to 140.
In the porous tube diluter, the sample is drawn through a porous tube, while dilution gas is introduced through the pores of the porous tube wall. The dilution gas acts as a sheath gas, which allows aerosol dilution without wall losses.
