Collection of particulates for analysis is known as what?

• A. Filtration
• B. Sampling
• C. Testing
• D. Analysis

Answer: (B)

Sampling is the act of taking a portion of material from a larger whole to analyze it. The key idea is obtaining a representative subset so you can infer what the whole thing looks like without testing everything. This fits the question because it’s about collecting particulates specifically for analysis. Filtration is about removing particles from a fluid, not about collecting a sample to analyze later. Testing is the actual measurement or assay performed on a sample. Analysis is the broader process of interpreting those results. In infection control, you collect air or surface samples so they can be analyzed in a lab to assess contamination levels, making sampling the correct concept.
