Course Objectives:

This course is designed to introduce the seniors and graduate students to the principles and techniques of aerosol measurement. Students will learn the basic skills of aerosol measurement in a variety of application areas, including air pollution and industrial hygiene measurements:

  1. To teach principles of air movers and flow calibration.
  2. To compare respirable and total mass concentration measurements.
  3. To study aerosol sampling and transport loss and efficiency of air sampling filters.
  4. To teach principles of inertial impactors and electrostatic low pressure impactor.
  5. To teach the principles of differential mobility particle sizer.
  6. To teach the principles of optical and laser particle counters.
Course Outcomes:

(Numbers shown in brackets are linked to program outcomes 1-9.)

  1. Apply air movers to collect particle samples and transport aerosols. [2,3]
  2. Understand standard test methods for sampling respirable mass used in industrial hygiene as well as EPA’s PM2.5 and PM10 air quality standards. [7,8,9]
  3. Apply inertial impactors for supermicron particle size distribution measurement. [2, 4]
  4. Apply differential mobility particle sizer for submicron particle size distribution measurement. [2,4]
  5. Apply optical and laser particle counters for particle size distribution measurement larger than 0.1 µm particle diameter. [2,4]
  6. Assess air quality in atmospheric and workplace environments. [5,6]
  7. Learn instrument calibration and measurement uncertainties. [1,5,6]

Assessment Tools:

  1. Six laboratory reports
  2. Two exams: mid-term and final exams
