When should composite wipe samples be used?

• A. Controlling cost is essential
• B. You need precise single-location data
• C. You expect large variations in dust levels between rooms
• D. You want to maximize data per location

Answer: (A)

Composite wipe samples are used to control costs by combining multiple surface areas into one analysis, which reduces the number of lab analyses and overall expense. This approach works well when you’re doing broad screening across many rooms or locations and don’t need precise data for each individual spot. It’s less suitable when you need exact, location-specific results or when you expect large differences between rooms, because a composite sample can mask hot spots and hide where contamination is highest. So, use composite sampling when cost control is the priority.
