1.2. Vapor Phase Analysis

Try these first

1. 1.

   What is vapor phase analysis?

   Hint

   Think about what we are trying to measure in the air.

2. 2.

   Define grab sampling.

   Hint

   What happens when you take a sample right away?

3. 3.

   What is the main purpose of vapor phase analysis?

   • To measure gases in the atmosphere
   • To measure particulate matter
   • Both A and B

   Hint

   Remember the definition of vapor phase.

4. 4.

   True or False: Grab sampling can be used effectively far from the emission source.

   • True
   • False

   Hint

   Consider where concentrations would be highest.

5. 5.

   Design a comprehensive monitoring plan using both grab and accumulation sampling techniques to assess air quality around a major highway. Include considerations for time of day, weather conditions, and expected pollutant types.

   Hint

   Think about when cars emit the most pollutants.

6. 6.

   If you are losing volatile compounds during the extraction phase of accumulation sampling, what strategies could you implement to minimize these losses?

   Hint

   What can you control during the extraction process?
