The VKL 10 series of dilution systems can reduce the concentration of aerosols by the dilution factor 01:10, also of very highly concentrated aerosols, in a defined and reliable way. The Palas® VKL 10 dilution systems are used in vertical operation for the particle size range up to 20 µm for powders and dusts. Dilution factors of up to 1:100,000 are achieved by cascading several VKL systems.
Dilution system – LDD 100
The dilution of large droplets is particularly important when measuring highly concentrated droplet aerosols. Since large droplets are difficult to dilute, standard systems only work up to a size of 1 – 2 μm. The newly developed dilution system LDD 10 (dilution factor 10) is the first system to dilute almost loss-free large droplets up to 10 μm.
