Effective Comparison of Yeast Extracts Using High Resolution GC and GCxGC-HRTOFMS
David E. Alonso and Joe Binkley

The Pegasus GC-HRT and GC-HRT 4D instruments are effective tools for the comprehensive analysis of yeast extracts.
• Enhanced chromatographic resolution of the HRT 4D system facilitated compound characterization by improving spectral similarity scores
• High quality data resulted in excellent spectral similarity scores when compared to large, well-established databases (NIST, Wiley)
• High resolution, accurate mass data was crucial for determination of fragment, molecular, and adduct

Performance Characteristics of a Comprehensive Two=Dimensional Gas Chromatography-High Resolution Time-of=Flight Mass Spectrometry System (GCxGC=HRTOFMS) Utilizing Chemical Ionization
Jonelle Shiel, Mark Merrick, Scott Pugh, Matthew Soyk, and Viatcheslav Artaev

Combining comprehensive two-dimensional gas chromatography (GC×GC) with a High Resolution Time-of-Flight Mass Spectrometer and Chemical Ionization is a powerful tool for compound identification. Performance of the LECO Pegasus GC-HRT 4D using Chemical Ionization (CI) was demonstrated using Benzophenone and Diesel. GC×GC separation results in narrow peaks, therefore, a high speed detection system is necessary.

Non-Target Analysis of Electronic Waste Samples from China
Jonathan D. Byer, Ed Sverko, Kurunthachalam Kannan, Qian Wu, Joe Binkley

GC×GC-HRT is a powerful tool for the comprehensive analysis and
chemical characterization of analytes in complex matrices. The combination of high resolution front-end separation with high
resolution time-of-flight mass spectrometry made possible the
identification of compounds previously unknown in these samples.

The Prestwick Chemical Library (R), A Valuable Tool for Screening
Jean-Marie Contreras1, Christophe Morice1, Jean-Marc Simon1, Bruno Didier2, Marie-Louise Jung1 and Thierry Langer3

The Prestwick Chemical Library® (PCL) is Prestwick’s flagship product dedicated to screening. It is a collection of 1280 molecules comprising 100% approved drugs (FDA, EMEA and other agencies) selected for their high chemical and pharmacological diversity. The PCL was designed to reduce the risk of "low quality" hits and therefore the cost of the initial screening, and appears to be an efficient smart library for hit discovery. The PCL comes with an extended fully-annotated database.

System-Specific Periodicity in qPCR Data and its Impact on Quantitation
Joel Tellinghuisen,1 Stefan Roediger,2 Thomas Volksdorf,3 and Andrej-Nikolai Spiess3

In some commercial qPCR instruments, the fluorescence signal shows reaction-to-reaction periodicity in all cycles, and this translates into periodicity in threshold-based Cq markers.
