Find out how the use of Comprehensive Two-Dimensional Gas Chromatography (GC×GC) with Time-of-Flight Mass Spectrometry (TOF-MS) demonstrates excellent matrix-analyte and analyte-analyte separation quality of a high number of target pesticides, at high sensitivity.
The tomato is the second most important vegetable crop next to potato. Global tomato production is currently around 130 million tons. The top 5 largest tomato producers are: China, EU, India, US and Turkey. They account for 70% of global production. Most of the fresh tomatoes are immediately processed into products such as juice, puree, and paste, ketchup/sauce, and canned whole. Pesticide residues in such products can cause a number of adverse health effects. Therefore, the accurate and robust identification and quantitation of pesticides is highly important.
The use of Comprehensive Two-Dimensional Gas Chromatography (GC×GC) with Time-of-Flight Mass Spectrometry (TOF-MS) demonstrates excellent matrix-analyte and analyte-analyte separation quality of a high number of target pesticides, at high sensitivity.
The LECO Pegasus BT4D was used to develop a robust and straightforward quantification workflow adhering to SANTE requirements.

Determining Terpene Profiles of Cannabis Strains Using GC and GCxGC with High Performance TOFMS
Cannabis is a complex mixture of compounds (>500) including cannabinoids, terpenes, terpenoids, non-cannabinoid phenols, nitrogenous compounds, flavonoids, and contaminants such as residual solvents and pesticides. It is the total composition of cannabis that is important in determining its potency and medicinal effectiveness. In this study, a novel analytical approach was utilized for the effective characterization of terpenes in different cannabis strains.
Quantitation and Non-Target Detection of Pesticides in Spinach Extract with Pegasus BT 4D
The increase in separation efficiency afforded by GCxGC allows for the separation of target analytes from matrix interferences. This application note demonstrates how, combined with the sensitivity available with LECO's Pegasus BT 4D, the ability to achieve required limits of detection, while minimizing matrix interferences to allow successful quantitation and effective identification of non-targeted pesticides is achieved.
