3.3. Condensation Particle Counter (CPC)

Try these first

1. 1.

   What does a Condensation Particle Counter (CPC) measure?

   Hint

   Think about what happens to tiny particles in a vapor.

2. 2.

   Why is knowing chemical composition important?

   Hint

   Consider what we learn from different measurements.

3. 3.

   What is the primary function of a CPC?

   • To measure temperature
   • To analyze particle size
   • To measure particle composition

   Hint

   Consider what aerosol means.

4. 4.

   True or False: The particle size measured by a CPC is the same as the aerodynamic diameter.

   • True
   • False

   Hint

   Think about how each method works.

5. 5.

   You are tasked to measure ultra-fine particulates around a major highway using a CPC. Describe the process and challenges you might face.

   Hint

   Consider the factors affecting air quality correlations.

6. 6.

   Explain how the choice of measurement method (CPC vs DMA) would affect your results when studying urban air quality.

   Hint

   Think about what each method tells you about the particles.
