In order to achieve a sufficiently high particle number concentration over the entire test range from 0,04 µm to
0,8 µm it may prove necessary to use several jet nebulizers with differing concentrations of the aerosol substances in the solvent. Numerical concentrations which are too high can be adjusted by diluting the test aerosol before the test filter mounting assembly. The number concentration in the test aerosol shall be selected so that no dilution is necessary for the measurements made downstream from the filter. A pump positioned downstream draws the test aerosol through the test filter mounting assembly. This ensures that the differential mobility analyser can always operate under nearly the same conditions, independent of the pressure drop across the tested filter medium. In contrast, where the testing system operates with an overpressure this ensures that leaks in the system do not falsify the test measurements. Particles are counted upstream and downstream from the filter using either two condensation nucleus counters in parallel, or using only one such counter to measure the upstream and downstream concentrations alternately. If the level of the upstream number concentration exceeds the measuring range of the counter then a dilution system shall be included between the sampling point and the counter.
1) Actually, the adjustment gives the mode of number distribution. This can be taken as equal to the median value with sufficient accuracy. SIST EN 1822-3:2010
