INDUSTRIAL EMISSIONS POLLUTION CHECK Stack Impactors Multistage Impactor for PM10 and PM2.5 mod. MSSI MAIN CHARACTERISTICS  Multistage cascade impactor, realized according to ISO23210-2009 norm for the nozzle dimensioning.  3 particulate cut size during the same sampling: Standard version  Fraction > 10 micron.  Fraction from 2,5 to 10 micron.  Fraction below 2,5 micron PM4 impactor version.  Fraction > 10 micron.  Fraction from 4 to 10 micron.  Fraction below 4 micron.  Available in Titanium or in stainless steel AISI 316. fig. 1 Assembled Impactor with nozzle and cone for sampling in vertical position fig. 2 Assembled Impactor with nozzle for sampling in horizontal position MSSI impactor is realized according to ISO23210 norm for the nozzle dimensioning. The impactor allows the simultaneous determination of total dust, PM10 and PM2.5 fractions (PM4 stage also available). The impactor can be supplied with two different inlet cones to allow the vertical and horizontal sampling, depending on the stream direction into duct (fig. 1 and 2). The impactor is designed for a high sampling flowrate, about 2 m3/h, depending on emission characteristics, to reduce sampling time. The device is supplied with a dedicated software, which allows to calculate sampling flowrate, nozzle and others factors to optimize the quality of the measurement. The Titanium impactor allows to determine the gravimetric fraction and to perform the chemical analysis (i. e. heavy metals determination) on the filters as well.
