Discovery Workflow Best Practices for Environmental Contaminants
When you don't know what you're looking for, as is often the case with environmental contaminants and pollutants, the task can seem daunting, but high-resolution TOFMS and GCxGC is a powerful combination for non-target searches. With the tools included with the Pegasus® HRT4D and the Multi-Mode Source™ (MMS™), identification of unknowns can be vastly improved and assigned higher confidence. |
GCxGC Analysis Workflow with ChromaTOF Tile
Small time savings throughout the workflow can add up to big savings. See aroma and flavor examples of how automated sample prep and elevated Time-of-Flight Mass Spectrometry (TOFMS) analysis, followed by software solutions to compare and evaluate data and results, can save your lab time and resources. |
Fast GC/Hydrogen Method Transfer – Overview and Examples
Helium is becoming an increasingly limited natural resource; using Hydrogen to achieve increased chromatographic throughput in GC applications is attractive. Both have advantages and disadvantages. LECO experts investigated the use of Hydrogen as a carrier gas for GC-TOF-MS analysis. Nick Jones, LECOs Global Application and Development Director (Separation Sciences) presents the method transfer approaches used, the technological benefits, and application examples in the presentation below. |
Environmental Forensic Investigation of Wastewater Applied to Agricultural Fields – What Do We Not Know, and How Do We Find It?
How do we find what we don't specifically look for? This presentation will look at non-target GCxGC for environmental forensics, or exposomic analysis, of wastewater, specifically the semivolatile organic fraction, and what can be done when discovered non-targets may present health impacts.

Application of Two-Dimensional Gas Chromatography with Mass Spectrometric Detection for Analysis of Pesticide Residues in Foodstuffs
The Czech Agriculture and Food Inspection Authority has been using GCxGC-TOFMS for the analysis of pesticide residues in food of plant origin since 2005. Radim Stepan will talk about the advances in the instruments and the analyses they have used for pesticide residue analysis in cooperation with the University of Chemistry and Technology Prague. |
Food Safety: A Journey Beyond the MOSH&MOAH Hump in Food Determination
The current analytical method for the quantitative determination of Mineral Oil Saturated Hydrocarbons (MOSH) and Mineral Oil Aromatic Hydrocarbons (MOAH) is LC-GC-FID, but the chromaticagraphic profile obtained is too often just a hump of unresolved substances. However, GCxGC-TOFMS/FID is the most promising solution to characterize MOSH and MOAH in detail and to detect markers that can help identify and act on the source of contamination. Giorgia Purcaro [University of Liege] will introduce the challenges of MOSH/MOAH analysis and talk about what adding a GCxGC-TOFMS analysis to your process can do for your results. |
