About this course:

Knowledge of the size and size distribution of particles in any air/gas filtration operation is of paramount importance in the selection of the most appropriate filtration and separation technology. This course will provide an introduction to aerosol/gas borne particle characterization technology, along with the latest commercially available technologies. Given the broad choices in particle characterization technology, the student will acquire the knowledge necessary for selecting the most appropriate technology and perform data interpretation and validation to obtain reliable data.

Learning Objectives – After taking Particle Characterization Technology for Air/Gas Filtration, learners will understand:

• Particle size data representation (number, surface, volume distributions)
• Aerodynamic diameter vs. physical diameter
• Importance of sampling and maintaining a well dispersed sample
• Physical principle, including strengths and limitations of the various particle sizing techniques
• Proper instrument selection
• Instrument evaluation
• Data interpretation and validation

Outline:

• Basic Concepts
• Distributions, and averages
• Sampling and particle dispersion
  Techniques (ensemble, separation and single particle counting technologies)
• Laser diffraction, time of flight, impactors, screening, optical particle sensing, dynamic image analysis
• Case study for instrument evaluation – laser diffraction
• Proper instrument selection and data validation and interpretation

Who should attend:

This course is designed for anyone involved in the operation/selection/specification of air/gas filtration systems as well as for technologists and practitioners interested in broadening their knowledge in aerosol particle characterization technology.

Instructor:

Dr. Trottier is a consultant in particle characterization & powder technology. He is the world-renowned particle characterization expert and retired from Dow Chemical in 2021. . He is one of the very few experts who has been applying particle measurement expertise to solve actual industrial challenges. Over the past 35 years, he published articles on particle characterization, and frequently presented courses globally. He also has extensive industrial experience in solids processing, and in the development and implementation of various particle characterization technologies.

Remi received his BSc. in 1983 and MSc. in 1987 from the department of Applied Physics and Astronomy at Laurentian University in Sudbury, Ontario, Canada. He received his Ph.D. from Loughborough University of Technology in the UK. His thesis work consisted of studying and modeling gas filtration from both experimental and theoretical perspectives.
