Dekati PM10 impactor is a three stage cascade impactor for determining particle gravimetric mass size distribution. The impactor size classifies particles into four different size fractions; in each size fraction the particles are collected on a filter that is analysed gravimetrically or chemically after the measurement. The impactor cutpoints are 10, 2.5 and 1 µm; if needed some of the stages can be removed from the assembly to make a simpler setup. The PM10 impactor is available with two different sample flow rates, 10 or 30 l/min. The particles are collected on Ø25 mm substrates on the impactor stages, and a 47 mm filter on the back up filter stage. Different material substrates are available from Dekati.
The Dekati PM10 impactor is an ideal choice for applications where some information on the particle size distribution is needed. Typical applications for the PM10 impactor include air quality measurements and power plant stack emission monitoring.
