1.5. Monitoring methods for Air PM - Part 2

Try these first

1. 1.

   What is gravimetric measurement?

   Hint

   Think about how we measure things based on weight.

2. 2.

   Name one advantage of using optical methods.

   Hint

   Consider ease of use and speed.

3. 3.

   What does gravimetric measurement primarily assess?

   • Concentration of PM
   • Size of PM
   • Shape of PM

   Hint

   Focus on what gravimetric measurements deal with.

4. 4.

   True or False: Calibration can be skipped if you trust the instrument's initial setup.

   • True
   • False

   Hint

   Consider how accurate you want your measurements to be.

5. 5.

   Evaluate how the choice of filter media can affect both mass measurement and chemical analysis of PM.

   Hint

   Analyze the implications of the materials used in filters.

6. 6.

   Design an experiment that compares the results from gravimetric measurements with those from optical methods using standard calibration particles.

   Hint

   Focus on standardization to ensure a fair comparison.
