Abstract
The characteristics of the sample air flow influence some properties of single particle optical counters. The direct measurements of these effects are difficult. In this paper two indirect methods to study these characteristics have been considered. In one method the pulse interval distribution is measured and this is compared with the theoretical distribution. As a result, one can recognize the possible recirculation and the oscillating sample air flow. The other method uses the pulse width distribution to indicate the homogeneity of air flow. The pulse width distribution can also be used to determine the volume of the viewing region. The experimental measurements show that these methods give information about properties and faults of the air flow systems.
