The spore trap type air sampling cassette is known as a sampling device created for the quick analysis along with collection of a broad range of flying aerosols. These include fungal spores, inorganic particulates,, fibers, skin cell fragments, insect parts along with pollen. Air enters the cassette, the particles come to be impacted on the sampling substrate, so the environment leaves throughout the exit orifice. The airflow and patented cassette housing are intended in such a manner that the contaminants are sent out and also deposited just as on a unique glass slide found in the cassette housing named the “trace.” Benefits: Useful for original website testing, particularly if fungal growth isn’t apparent.
Drawbacks of the Spore trap method:

So what if spore traps cannot tell species’ differences?
Because so many water intrusion molds are exactly the same in a microscope, a spore syringe analysis cannot provide species differentiation. Consequently, a comparison of outdoor and indoor samples will not provide info on the actual differences between samples, just TOTAL counts of spores that look similar. Consequently, if a certain household sample has got the exact same total counts as an outside sample though the species will vary, the assessment would probably miss a moisture related mold condition. This is because a spore traps ASSUMES the species variations are exactly the same from a certain range of outdoor and indoor samples. Remember: A spore trap count won’t recognize various species of Penicillium or Aspergillus in a pair of outdoor and indoor samples.
Do not spore traps accumulate spores in the size range of many water intrusion molds?
No. The spore trap is an impaction collector. The collection effectiveness of a spore trap is based upon both air flow rate and also the physics of impaction. In a nutshell, spore traps don’t capture fungal spores below three to four microns in diameter. What this means is that the majority of species of molds of Penicillium and Aspergillus are collected at really low prices in standard spore traps than larger molds. This particular phenomenon is a well known but little discussed fact in the lab community.
