The MCE Cassette can be used for which sampling applications?

• A. Dust samples only
• B. Spore trap samples only
• C. Air velocity measurements only
• D. Both spore trap samples and dust samples

Answer: (D)

An MCE cassette works because it uses a membrane filter to capture airborne particulates as air is drawn through it. That makes it versatile for dust sampling, where you collect ambient dust on the filter for gravimetric or chemical analysis. It also serves as a spore trap, since fungal spores and other particles collected on the filter can later be identified under a microscope or cultured. It isn’t a velocity-measurement device—air velocity is determined with tools like an anemometer. So this cassette can be used for both spore trap samples and dust samples.
