2.7. Design Considerations for Sampling Systems

Try these first

1. 1.

   What does adsorption refer to?

   Hint

   Think about how a sponge soaks up water.

2. 2.

   Name an example of an adsorbent material.

   Hint

   Consider what materials are used in air purifiers.

3. 3.

   What is adsorption?

   • The process of removing particles from air
   • The process of molecules adhering to a surface
   • The process of releasing gases from liquids

   Hint

   Remember that adsorbents catch on to analytes.

4. 4.

   True or False: Breakthrough indicates successful trapping of analytes.

   • True
   • False

   Hint

   Think about what it means when you miss collecting something important.

5. 5.

   You are tasked with designing a sampling system for a new air quality project. Discuss how you would select the adsorbent and control flow rates to ensure optimal sampling efficiency.

   Hint

   Consider both the chemical properties of the adsorbent and the physical constraints of your sampling system.

6. 6.

   How would you modify an existing sampling design if breakthrough has been observed during initial tests at specific flow rates?

   Hint

   What relationships exist between flow rates and adsorbent effectiveness?
