3.2. Differential Mobility Analyzer

Try these first

1. 1.

   What does DMA stand for?

   Hint

   Think about particle analysis tools.

2. 2.

   What is the purpose of the CPC?

   Hint

   It helps in measuring very small particles.

3. 3.

   What is the function of a Differential Mobility Analyzer?

   • To measure temperature of aerosols
   • To classify particles based on their size
   • To count the total number of particles

   Hint

   Consider how the sense of size plays a role in DMAs.

4. 4.

   True or False: The aerodynamic diameter and scattering diameter are always the same.

   • True
   • False

   Hint

   Think about what each diameter measures specifically.

5. 5.

   Explain how a Differential Mobility Analyzer could change air quality assessments in urban planning.

   Hint

   Consider how accurate data can lead to better decision-making.

6. 6.

   Design a small experimental approach using both DMA and CPC to analyze air quality in a busy city junction. Detail your methodology.

   Hint

   Think about capturing data over varying periods to grasp fluctuation trends.
