Collect, microscope.: Pollen counting involves collecting the pollens and molds on specialized rods, or in special traps. These counters measure a set volume of air over a period of time. The rods are stained and examined under a microscope. Pollens have different characteristics that allow experts to label them as grasses, trees or weeds. Mold spores tend to stain differently and can also be identified.

A couple ways: 1.A silicone grease-covered rod, rotated in the air to collect the pollen. The rod is then removed and taken to a lab where pollen s analyzed and measured. 2. Burkard Trap, This device faces towards the wind and draws in air by using a pump. Pollen particles drawn in are then trapped by a sticky wax film that is attached to a rotating drum. The drum slowly rotates and pollen is analyzed.
