A Reduced Workflow Solution for the Analysis of Gamma-Hydroxybutyrate (GHB) in Human Hair Samples Via an Automated Bead Mill as a Precursor to GCxGC-TOFMS and GC-HRT
Brittany M. Watt, David E. Alonso, Joe Binkley, Jeff Patrick, Frank A. Kero, Victor Vandell, Elena Gairloch, Brad Nolt, Tom Enzweller, Rhys Jones, Lee Williams, Karen S. Scott

- The Biotage Bead Ruptor 24 was effective in pre-treating hair samples prior to the extraction procedure.
- The enhanced chromatographic resolution of GCxGC-TOFMS and high resolving power of GC-HRT minimized interferences and facilitated accurate analysis of GHB in hair.

A FastGC Proton-Transfer-Reaction Quadrupole Ion Guide Time-of-Flight (PTR-QiTOF) Mass Spectrometer
Alfons Jordan1, Lukas Märk1, Jens Herbig1, Christian Lindinger1, Rene Gutmann1, Lukas Fischer1, Eugen Hartungen1, Simone Jürschik1, Gernot Hanel1, Philipp Sulzer1, Tilmann D. Märk1,2

In order to identify and quantify isomeric compounds independently in real-time, we introduce a novel approach where we integrate a fast GC column (“fastGC”) into a PTR-QiTOF instrument. The outstanding sensitivity of the new PTR-QiTOF (up to 4,700 cps/ppbv) is crucial for applications where time per analysis is limited, e.g. nosespace in food and flavor research. Particularly, in these fields the chemical environment is normally very complex so that a high selectivity is essential as well.

Analysis of Polymers, Additives and Contaminates in Medical Devices using Pyrolysis-GCMS
Gary Deger

Pyrolysis GC-MS is a standard technique used to analyze industrial polymers. This poster will show the use of multiple temperature ramps to analyze for additives and contaminants, in addition to polymer identification, in several medical devices.

An investigation into the effects of aging on automotive bumper samples by xylene soluble flow injection polymer analysis (XS-FIPA)
Bassem Sabagh, Wei Sen Wong, Bernd Tartsch

This poster describes the use of flow injection polymer analysis (FIPA) as an analytical tool for xylene soluble (XS) determination with quick and easy simultaneous measurements of molecular weight (MW), intrinsic viscosity (IV) and XS%. The technique was applied to automotive bumper samples which had undergone an aging test. The results from the XS-FIPA technique highlight the differences caused by the aging process.

When Single Dimension GC Separations Fail: Exploring Real World Applications for Comprehensive Two=Dimensional GC (GCxGC)
Joe Binkley, Elizabeth Humston-Fulmer, David E. Alonso, and Lorne Fell

Examples will be highlighted for food/flavor/fragrance, metabolomic, and petrochemical application markets. The advantage in number of compounds detected and overall quality of their mass spectral library similarity scores, as compared to one-dimensional methods will be clearly demonstrated.

Busted! First Detection of Steroid Hormones in Pacific Walrus Bones
Charapata P, Horstmann L, and Misarti N

The Pacific walrus (Odobenus rosmarus divergens) is a candidate species for the Endangered Species List because Arctic sea ice has declined significantly in the past decades. This project focuses on validating a method for extracting steroid hormones from archaeological, historical, and modern bone creating a baseline of hormone levels during different climate regimes.

Uncertainty estimation of an analytical method for analysis of fumonisin B1 in four types of rice intended for consumption human
Petrarca, M.H.; Rossi, E.A.; Sylos, C.M.

The expanded measurement uncertainty of a sample preparation method based on QuEChERS procedure for the determination of fumonisin B1 in four types of rice, using HPLC-FLD after precolumn derivatisation with ortho-phthaldialdehyde, was estimated from in-house validation data.
