Get introduced to cleanroom basics, including a review and comparison of ISO and FS209E classifications. Review particle size, composition, types and sources, and discuss commonly used measurements to define the size of irregularly shaped particles and the implication of each technique. Additionally, you will explore particle concentrations in liquid and air samples.
Understand particle behavior by reviewing transport characteristics, interactions and various forces on particles. Get an introduction to filtration mechanisms and filter efficiency curves for air and liquid systems, and learn about the role played by the refractive index, particle size and shape. In addition, the principles of Rayleigh and Mie light scattering will be covered, including basic scattering relationships.
Fundamentals of Optical Particle Counters
This presentation introduces the fundamentals of optical particle counters (OPCs). Topics include OPC design and specifications, industry nomenclature, laser light and detector basics, instrument types and a discussion on sensor resolution and accuracy. The objective of the presentation is to establish a common background and language that will contribute to a better functional understanding of optical particle counters.
Monitoring Particles in Air
Get an introduction to the types of particle counters used to monitor aerosol particles. A comparison between mobile, fixed and sequential monitoring, along with the advantages and disadvantages of each method, will be covered. Additionally, specialized applications and possible types of devices to monitor those applications will be discussed. Equipment includes particle counters, spectrometers, monitors and sensors.
Particle Transport and Sampling
Different aerosol particle sampling methods utilize a length of tubing to transport samples to a particle counter. Learn how tubing affects particle counts, and see the effect short tubing length has on particle transport losses.
Advanced Light Scattering
Take an in-depth look at Mie, Rayleigh and other theories of light scattering, and discuss the origins of the equations and how they were derived. Additionally, take a closer look at the influence particle size, refractive index and shape have on scattering intensity.
Cleanroom Certification and Products
Did you know that the particle counter you use could impact the certification process? This course discusses the differences between cleanroom certification and monitoring and what is required to perform a cleanroom certification, including an overview of ISO 14644-1 and 14644-2.
Particle Counter Data Interpretation
Understand system reports, interpret data and conduct trend analyses, set alarm limits and improve process control.
