title: Sampling characteristics of the Rotorod, Rotoslide and Andersen machines for atmospheric pollen and spores.
abstract: This study shows the superior aeroallergen collecting capabilities of the Rotorod sampler compared to the Rotoslide, Andersen and Durham devices. It collected the largest number and greatest variety of pollen grains and spores. Particle-size distribution was about 150 micron to 2.5 micron. Water wash-off was best prevented by the Rotorod's retracting rod-holders.
