Venacontra Ejector Diluter (VC-ED) is designed to be used in aerosol sampling when efficient and rapid mixing is needed. It is especially suitable to be used as secondary diluters as it stabilizes the flow rates. It offers moderate dilution ratios with high sample flows. Special attention has been given to designing of the ejector nozzle, which is not easily blocked with aerosols containing high concentrations and condensable vapours.
The operating principle of the ejector diluter is based on the high speed of pressurized dilution gas flow around an ejector nozzle. This causes a pressure drop that draws the aerosol sample through the nozzle, and subsequently mixes with the sample aerosol stream with the dilution gas flow.
