Comparing Additives and Other Extractables From Primary and After-Market Cell Phone Cases by High Resolution Gas Chromatography Time-of-Flight Mass Spectrometry
Christina Nieh, Jeff Patrick, and Joe Binkley

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.

Exploring the Ionization Space in Traditional Electron Ionization with High Resolution GC=TOFMS for a Variety of Compound Classes
Jonathan D. Byer, David Alonso, Joe Binkley, Charles Lyle, and Jeff Patrick

-Source temperature was commonly the most significant variable for maximizing molecular ion peak area.
-Chromatographic peak shape was temperature dependant primarily for the non-volatile compounds.
-Ionization conditions were optimized to maximize molecular ion for a variety of compound classes.
-Ionization conditions do change the peak shape and peak area, which relates directly to library searchability.

Analyzing the GCMS amenable compounds in water matrices according to the European Water Framework directive ( 2013/39/EU)
Inge de Dobbeleer, Joachim Gummersbach, Paul Silcock

Purpose: An overview of the results of GC amenable compounds is given for EU 2013/39/EU
Methods: For the volatile compounds headspace GCMS was used; for the semivolatiles liquid liquid
extraction was applied followed by GCMSMS detection.
Results: The detection limits are calculated by standard deviation and there are some linearity examples. Not all compounds are listed in this poster, but a full list is available.
