3.4. Scanning Mobility Particle Sizer (SMPS)

Try these first

1. 1.

   What does SMPS stand for?

   Hint

   What do the initials SMPS represent?

2. 2.

   Name one source of ultra-fine particulate matter.

   Hint

   Which common source of pollution generates very small particles?

3. 3.

   What does SMPS measure?

   • Only mass distribution
   • Particle size and composition
   • Only chemical composition

   Hint

   Think about what parameters are important for assessing air quality.

4. 4.

   True or False: SMPS can measure particles as small as 10 nanometers.

   • True
   • False

   Hint

   Recall the size range covered by SMPS.

5. 5.

   You are tasked with conducting a study on air quality in a city. Explain how you would use SMPS to understand pm composition and what challenges you might encounter.

   Hint

   Think about both the practical application and the theoretical aspects of particle measurements.

6. 6.

   Discuss a scenario where measuring ultra-fine particles could reveal significant public health issues in a metropolitan area. Provide examples of data you would seek.

   Hint

   Consider the implications of data collection on public policy.
