Original Event Date: Tuesday, December 17, 2013
Duration: 60 minutes
Presenters: David Exline, Senior Vice President & Antonio Scatena, Laboratory Manager at Gateway Analytical
Host: Shawn Wilhelm, Marketing Coordinator at Gateway Analytical
Highlighted Topics Covered:
- An overview of analytical methods used to characterize materials.
- Present a basic multi-tiered analytical approach to material characterization
- How to solve product contamination issues using a scientific approach
- The use of microscopy and spectral databases to identify a component of a material
- Commonly encountered problems with characterizing a material in a mixture
There are many challenges to the characterization of materials. The main reason for this is the combination of several materials that make up an end product. Unlike known component libraries, pure components are rarely in a “real world” environment when attempting to identify materials. Whether the goal is to identify a material, determine failures and product defects, perform reverse engineering investigations, identify foreign materials or maintain quality of the product, the understanding of mixtures is critical in this analysis. To fully understand a material, one must understand the process and environment in which the product is made.
During this webinar, our presenters discussed the analytical methods used to characterize materials and the use of multi-tiered analytical approaches to fully characterize a material. They reviewed the use of microscopic and spectroscopic techniques that enable scientists to better understand the main components of a material. They also discussed utilizing this information to separate components into discreet portions for examination and comparison to investigate products.
