Optimization of a Vacuum Ultraviolet Photoionization source for Gas Chromatography used with a High Resolution Time of Flight Mass Spectrometer
Lloyd Allen and Viatcheslav Artaev

-Tune solution allows optimization of ion source parameters for
both proton transfer and direct ionization
-Independent ionization processes exist for M+ and MH+
-Optimizing for dopant signal intensity yields inferior results
-Degree of fragmentation remains relatively constant over a
range of source conditions

Analysis of Organic Marker Compounds and Hazardous Organic Compounds by GC/MS to Identify Contamination, Counterfeiting and Adulteration of Spices
Patricia Atkins

Our previous study of spices was designed to evaluate the metal content in the spices for evidence of contamination by heavy metals or for adulteration and counterfeiting by notable concentrations of wear or additive metals. This study targeted the same spice samples to quantify the characteristic primary and secondary market compounds for each spice group.

A Novel Benchtop Time-of-Flight GC-MS System for High Performance Analysis of Human Urine
David E. Alonso, Joseph E. Binkley, Lorne M. Fell

A workflow was developed and implemented for the effective comparison of urine. It involved the preparation of stable compounds through derivatization, data acquisition using a high performance benchtop TOFMS, comprehensive data processing (NonTarget Deconvolution™), and quick retrospective analysis of rich datasets using Target Analyte Finding.

Platform Agnostic Data Processing Routine for Targeted and Untargeted Metabolite Identification in Drug Discovery
Richard Lee,1 Vitaly Lashin,2 Andrey Paramonov,2 Alexandr Sakharov,2 Alexey Aminov2

A discussion of a new informatics solution that addresses common challenges in metabolite identification and characterization--from LC/MS data processing and metabolites prediction to reporting and databasing of assembled biotransformation knowledge.

Accurate Mass Spectral Database: Harnessing the Power of High Performance Mass Spectrometry at Long Last
Lorne Fell, Viatcheslav Artaev, Kevin McNitt, Steve Robles, Albert Lebedev

Standard mixtures comprising of alkanes, PAHs, semivolatiles, and pesticides were analyzed using a high resolution time-of-flight (HRTOF) mass spectrometer—Pegasus GC-HRT (LECO Corporation, Saint Joseph,MI)—at 10 spectra-per-second (m/z40–300) in high resolution mode (25,000 at FWHH). The resulting chromatographic peaks were automatically found, deconvoluted, and curated into an Accurate Mass Library (AML).

Automated Sample Preparation of Whole Blood for Therapeutic Drug Monitoring and Diagnostics by LC-MS using a Commercial Autosampler
Christian Berchtold1, Irene Wegner1,Timm Hettich1, Reto Bolliger2, Guenter Boehm2, Goetz Schlotterbeck1

In this poster the parameters necessary to automatically prepare whole blood samples for online LC-MS applications in the field of diagnostics and TDM have been investigated. A strategy and the most important parameters are shown for the optimization of a PAL RTC autosampler
for the preparation of whole blood samples.
