Aerosol dilution and sampling

Because of isokinetic sampling requirements this has been the shape preferred for many years but now more and more users are switching over to rectangular shaped sampling probes because of the advantages they offer compared with circular inlets. Topas probes are manufactured with rectangular inlets on front of a smooth transition into a cylindrical tube. The design of this special probe is based on international draft standard ISO CD 14644 which specifies a maximum width to length ratio of 1:6. The Topas manufacturing process guarantees high-quality, smooth internal surfaces throughout the probe including all transition regions which minimises particle losses.
