Abstract

A device for determination of solid particle concentration includes a primary diluter (6), a downstream heated evaporator (7), a secondary diluter (8) downstream of the evaporator (7) and a particle counter (5). The secondary diluter (8) is a porous tube diluter and is mounted between the outlet of the evaporator (7) and a stabilization chamber (14), from which the sample flow is diverted to the particle counter (5).
