6.1. Multi-channel Sampling

Try these first

1. 1.

   What is a gravimetric measurement?

   Hint

   Think about how we measure weight.

2. 2.

   Name one optical technique used for measuring PM.

   Hint

   Consider methods that involve light.

3. 3.

   What measurement technique involves collecting particulate matter on a filter?

   • Optical Techniques
   • Gravimetric Measurement
   • Electrical Mobility

   Hint

   Think about how physical mass is quantified.

4. 4.

   True or False: Optical techniques can provide real-time data.

   • True
   • False

   Hint

   Reflect on the quick nature of light measurements.

5. 5.

   Design a comprehensive multi-channel sampling plan that includes gravimetric, optical, and electrical mobilities. Outline the steps and expected outcomes.

   Hint

   Consider how each method can complement the others.

6. 6.

   Evaluate a scenario where calibration did not occur properly among different measurement techniques. Discuss the potential impacts.

   Hint

   Think about how reliability affects decision-making.
