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.

Integrating Fluorescent Carbon Nanodot Synthesis and Optical Detection of Methylmercury
Carlos Bendicho, Isabel Costas-Mora, Vanesa Romero, Isela Lavilla

In the last years, a great interest toward development of optical nanoprobes has arisen, so fluorescent nanomaterials have been implemented in analytical systems for the detection of several species. In this work, a novel assay that integrates the synthesis of fluorescent carbon dots (CDs) and sensing within one step, for the fast, sensitive and selective detection of methylmercury is presented.

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.

Investigating the Effects of Commercial Antimicrobial Agents on Human Corneal Epithelial Cell Membranes
Ian J. Horner, Jerod J. Hurst, Nadine D. Kraut, Alyssa A. Rook, Crystal M. Collado, G Ekin-Atilla Gokcumen, and Frank V. Bright

Several commercial multi-purpose solutions (MPS) products contain polyhexamethylene biguanide (PHMB) and/or polyquaternium-1 (PQ-1) as antimicrobial agents. In this poster we report the effects of PHMB and PQ-1 on small unilamellar vesicles (SUV) that we have designed to mimic the average human corneal epithelial cell membrane.

Aptamer-Based Electrochemical Biosensing Platform for Detection of Hormonal Pollutants in Water
Contreras Jimenez, G.; Eissa, S.; Ng, A.; Zourob, M.; Siaj, M.

A novel detection mechanism based on aptamers has been developed to detect small molecules as hormones, antibiotics, toxins, drugs, etc. For first time, an aptasensor to detect progesterone has been developed.

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.

The role of AHPCO Technology in reducing allergic rhinitis cases as Air Purifier, Surface Sterilizer and Ice Maker sterilizer
Dr. Nabarun K. Ghosh, PhD1, Dr. Constantine K. Saadeh, MD FAAAAI2, Dr. Jeff Bennert, PhD CTN3 and Ms. Griselda Estrada, BS1

Dirty ice makers can cause potential health hazards. To prevent any potential contamination, the interior surfaces of the ice machine must be cleaned and sanitized regularly. This report justifies the demand and use of novel equipment that will sanitize the surface of an ice machine continuously. We evaluated the Bi-Polar® unit built by Air Oasis (1.2) in sanitizing the ice machine surface.

Tolerance to Allergenic Foods Following Food Oral Immunotherapy (FOIT)
AR Hague1, RL Wasserman1,2, SK Silvers1,2, RW Sugerman1,2, M Herbert3

We report on 21 patients who completed FOIT (food oral immunotherapy) escalation followed by a period of maintenance dosing and later underwent a tolerance FC (food challenge). 90% of tested FOIT patients and 94% of patients who met our pre-defined criteria for tolerance FC achieved tolerance to their allergenic food.
