Abstract
The invention relates to a condensation particle counter with a measuring device (1) and a method for particle measurement, wherein the measuring device (1) comprises a measuring channel (2) through which a particle-laden aerosol stream (8) flows, the measuring device (1) having an optical measuring device (3). comprises, the measuring radiation (6) emanating from a radiation source (4) along a main axis (5) enters the measuring channel (2) through an inlet section (7) during measuring operation, passes through the aerosol flow (8) in the measuring channel (2), by a Exit section (9) emerges from the measuring channel (2) and strikes at least one radiation detector (10) of the optical measuring device (3), at least one separating element (11) permeable to the measuring radiation (6) being provided, through which the measuring radiation ( 6) passes through during measuring operation, and wherein an exit of the aerosol stream (8) from the measuring channel (2) to the radiation source (4) and / or to the radiation detector (10) is prevented by the at least one separating element (11).
