Analysis of Terpenes Using Gas Chromatography with Vacuum Ultraviolet
The University of Texas at Arlington and VUV Analytics

The VUV absorption spectra for different terpenes were distinctive and differentiable. GC-VUV demonstrated the capabilities for qualitative and quantitative analysis of terpenes in turpertine mixtures. Chromatographic coeluting signals can be deconvolved by the VUV data analysis software.

Determination of C2-C12 Aldehydes in Water by SPME Arrow On-Fiber Derivatization and GC/MS
1 BGB Analytik AG, Lettenstrasse 97, 8134 Adliswil, Switzerland; 2 CTC Analytics AG, Industriestrasse 20, 4222 Zwingen, Switzerland

A method applying SPME Arrow extraction and on-fiber derivatization for the quantitation of C2-C12 aldehydes in water by GC/MS is described.
Assessing Diversity in Cassava through the Application of Metabolomics

In the present study metabolomic platforms have been established for Cassava and used to assess the biodiversity present in Cassava germplasm collections and elucidate underlying biochemical mechanisms associated with traits of interest.
PredRet: Prediction of Retention Time by Direct Mapping between Multiple Chromatographic Systems
Department of Food Quality and Nutrition, Research and Innovation Centre, Fondazione Edmund Mach, San Michele all’Adige (TN), Italy.; Department of Stress and Developmental Biology, Leibniz Institute

Retention time (RT) information is under-utilized in LC-MS based metabolomics and sharing of RTs between systems is not currently possible. PredRet is a new system that allows highly accurate mapping and prediction of RTs between LC systems.
Minimizing Carry-over for High Throughput Analysis
1FHNW Fachhochschule Nordwestschweiz, Hochschule für Life Sciences Gründenstrasse 40 CH-4132 Muttenz; 2CTC Analytics AG Industriestrasse 20 CH-4222 Zwingen; Switzerland

Minimal carry-over is a prerequisite for high throughput analysis. However, minimized carry-over and cycle time are competing and a careful optimization is mandatory. In this study the influence of wash conditions on carry-over of various compounds was investigated. A strategy to minimize carry-over was developed. The influences of different wash tasks were investigated. Finally the contribution of different system components such as injector valve or column was studied.
A Comparison of ITEX Dynamic Headspace–GC/MS to other Enrichment Techniques for Analysis of Flavoring Compounds
1Aspen Research Corporation, Maple Grove, MN; 2CTC Analytics, Zwingen, Switzerland

Enrichment techniques are commonly used for the analysis of flavoring compounds in different matrices with GC/MS. Analysis of flavoring compounds is done by purge & trap, SPME or headspace, depending on requirements for sensitivity. The In-Tube Ex¬traction (ITEX) Dynamic Headspace uses a micro trap filled with an adsorbent material to efficiently extract the compounds. Here we evaluate if the ITEX can be used to effectively analyze for these compounds and reduce the analyst’s time involved.

High Performance Comprehensive Two-Dimensional Gas Chromatography Coupled with a High Resolution Multi-Reflecting TOFMS for Confident Non-Target Analyte Identification
LECO Corporation, Restek Corporation

The use of comprehensive two-dimensional gas chromatography to help increase chromatographic resolution is a major step in tackling the problem of confident peak identification in a complex sample matrix. Combining the separation power of two-dimensional gas chromatography, with resolving power greater than 25,000, and sub ppm mass accuracies of a high resolution multi-reflecting TOFMS is the ideal solution to confident compound identification within a complex sample matrix.
Fragmentation Trees for Automated de novo Interpretation of Impure Electron Ionization Spectra from Gas Chromatographic Complex Mixture Analysis—Chemical Deconvolution
LECO Corporation, Mass Spectrometry Consulting Ltd., Moscow State University

-Chemical deconvolution algorithms accurately reported independent
components of dead coelutions where such components belong to distinct chemical classes.
-Present algorithms fail to distinguish chemically similar analytes such as branched and linear alkanes, thus chemical deconvolution is not a
substitute for GCxGC.
-Chemical deconvolution algorithms accurately rejected more than 80% of spurious signals from manually curated spectra found to be contaminated with unrelated signa
Effective Comparison of Yeast Extracts Using High Resolution GC and GCxGC-HRTOFMS
LECO Corporation

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
