Multistage Cascade Impactor Meets Increasing Requirements

In order to meet the increasing requirements toward the fine particulate determination and progressive reduction of emission dust concentration, Tecora (Italy) designed and produced MSSI, its multistage cascade impactor.

MSSI impactor is realised according to ISO 23210 norm and in compliance with EN 13284-1 norm, for PM10 and PM2.5 simultaneous determination.

The impactor is designed for high sampling flowrate, about 3 m3/h, depending on emission characteristic, to reduce sampling time.
Also, the impactor can be supplied with 2 different inlet cones, to allow vertical and horizontal sampling, depending on the stream direction into duct.

The standard supply includes a dedicated software which calculates the sampling flowrate, nozzle and other factors to optimise the quality of the measurement.

Tecora designed a new separation stage, with a PM4 cut point. It can be placed after the PM10 stage (removing the PM2.5 stage), in order to sample together PM10 and PM4 (thoracic) fraction, increasing MSSI potential.
