Try these first

1. 1.

   What is grab sampling?

   Hint

   Consider what helps in pulling air into containers.

3. 3.

   What is the primary purpose of grab sampling?

   • To measure temperature
   • To collect vapor samples for analysis
   • To capture particulate matter

   Hint

4. 4.

   True or False: Grab sampling works best when concentrations are low.

   • True
   • False

   Hint

   Consider the requirements for successful sampling.

5. 5.

   Hint

   Think about proximity to the emission source.

6. 6.

   Discuss potential losses during sample collection and how they might impact your analysis results.

   Hint
