  • Diluting is often one of the most crucial parts of the aerosol sampling and measurement systems.
  • For most aerosol measurement setups the target of the aerosol dilution system is to dilute and cool the sample suitable for the used analyzers and to preserve the sample as unbiased as possible.
  • Venacontra diluting sampling systems are designed to achieve these goals. They provide stable and adjustable flow rates and a well-conditioned dilution and mixing process which is essential in having well-defined sampling conditions with minimal sampling artefacts.
vc-das_tagiVenacontra Diluting Aerosol Sampler (VC-DAS) is a combination of the Venacontra Porous Tube Diluter and the Venacontra Ejector Diluter providing a flexible and reliable sampling system which operates well with process gases with very high particle concentrations, such as combustion or synthesized aerosols. It offers a wide range of dilution ratios with stable and adjustable sampling flow rates and a possibility to connect several analyzers into the same sampling system.

vc-hdas_tagiThe VC-DAS system is developed specifically for aerosol sampling from high temperature process gases. It is designed to quench chemical reactions and aerosol transformation processes inside the sampling probe with a special diluting probe tip developed by Venacontra, thus minimising potential sampling artefacts.

vc-ed_tagiVenacontra 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 payed for designing of the ejector nozzle, which will not get easily blocked with aerosols containing high concentrations and condensable vapors.

vc-ptd_tagiVenacontra Porous Tube Diluters (VC-PTD) are designed to be used in an aerosol sampling with wide range of dilution ratios and minimal losses. Diluters offer excellent diluting properties when gentle and reliable sampling is needed. The Venacontra Porous Tube Diluters are 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.
