To examine the error in measuring particle concentration due to anisokinetic sampling over a wide range of inertia parameters, theoretical and experimental studies have been conducted by using methyleneblue-uranine aerosol generated by a spinning disk and lycopodium spores in the small and large inertia regions, respectively. The theoretical results obtained assuming potential flow agree well with the experimental values in the small inertia region. On the other hand, the experimental result is smaller than the theoretical one in the large inertia region. It is also recognized that the concentration error becomes smaller as the sampling velocity becomes extremely high. The amount of particles deposited in a probe is also examined to show that this amount cannot be ignored in practical applications.
