Dilution systems

Aerosol dilution systems according to the ejector principle with temporally constant dilution factors of 1:10 up to 1:1.000.000
———
In practice, the aerosols to be measured very often have to be made measurable for the particle measurement devices with regard to the particle concentration by dilution.

The ejector principle is the classic among the dilution systems and is described in VDI 3491-15. It is particularly characterized by the combination (cascadability) of the individual dilution levels, which means that dilution factors of 10, 100, 1,000, 100,000 and 1,000,000 can be set reliably.

Depending on the model variant, the dilution levels for isothermal dilution of hot aerosols can be heated up to 200 °C. Stainless steel models can be designed pressure-resistant up to 10 bar overpressure and are used worldwide with great success for the measurement of chemically aggressive aerosols.

The Palas® dilution systems are robust, easy to use and provide a clearly defined dilution factor. The dilution factors can be checked by the user on site.
