Poster Information
Abstract: As the market for cell phone cases explodes with new forms and synthetic materials, the properties of quality and durability are paramount. At a chemical level, even small changes in the additives profile and polymer type create large differences in cost and physical properties. GC-HR-TOFMS analysis allows for non-targeted analysis of cell phone case extractables, revealing chemical profiles that can assist in assessing durability and quality of the plastics used, as well as identifying particular brand formulations.Summary: High resolution GC-TOFMS on the Pegasus GC-HRT allowed for quick and easy non-targeted screening of extractables from a common consumer product: the ubiquitous cell phone case. Most components could be identified with high similarity scores against commercial libraries. However, even when faced with low similarity scores against commercial libraries, such as in the case of Biphenol AF, the ability to rely on high mass accuracy allowed for confident identification of components.Report abuse »
