A. Burkholz, MEASUREMENT OF AEROSOL FRACTIONATION IN F LOWING AND STATIC GASES BY MEANS OF A PHOTOIMPACTOR, Staub, Reihhaltung der Luft, 54(6), 1994, pp. 233-237
A new method is presented for measuring aerosols in the range of 0.3 t
o 10 micrometers. The new method delivers the results immediately by m
easuring the aerosol portions which pass the impactor separation steps
with a photometer, while, with normal cascade impactors the evaluatio
n of the results is achieved by analysing the aerosol samples in the l
aboratory. The measuring procedure, the evaluation of the photometer s
ignals and the presentation of the results are controlled by a laptop
computer.
