Deep Dive Virtual Workshop 4. Filtration Analysis - 1. Data Collection
Filtration analysis using CT investigates a wide range of materials from filter media to complete filters. Because of the range of materials and sample sizes, data collection must be carefully considered. For example, samples may require either micro or nano-scale imaging to achieve sufficient resolution of filter materials. In this episode, we will go into the lab to investigate how to choose the best data collection geometry and data collection parameters. Then we will review how to collect high-quality CT images of filter media that can be used for digital filtration analysis.
In this workshop, you will learn:
- How to collect high-quality images of filter media
- How to evaluate your filter media data and assess suitability for fiber analysis
