Module 11: Sampling Instrumentation for Airborne Nanomaterials
Channel: METPHAST Program
Date: 23/06/2016

The objectives for this module are that, by the end, learners should be able to (1) categorize sampling instruments based on size resolution, time resolution, and concentration metric, (2) describe operating principles of different sampling instruments, (3) list methods used to analyze nanomaterial samples, and (4) interpret output from different instruments. Animations were created by Derek Siebert, Application Development, ITS, The University of Iowa.
