摘要：
Provided is a method and apparatus which enable only pollen existing in the atmosphere to be automatically quantified. According to the method and apparatus, particles other than those substantially smaller than pollen grains, contained in a given amount of atmosphere, are separated; the separated particles are caused to flow through a flow cell in such a state that self-fluorescence from each of the particles can be measured; self-fluorescence from each of the particles passing through the flow cell is measured; and the number of particles is counted based on a measured value.
