Abstract
A measuring system and process for measuring the size distribution of particles in an aerosol with a time-varying flow utilizing a measuring instrument that utilizes a time-invariant flow rate is provided. The process includes employing a vacuum source to establish a constant flow through the measuring instrument. The vacuum generated by the vacuum source is used to draw an aerosol stream through an inlet incorporating a second stream of relatively particle free gas. The first and/or the second stream may be adjusted so that at any instant of time, the sum of the two streams is a constant value equal to the flow rate through the measuring instrument.
