Chemical constituents on their wings provide cicadas with water resistance as well and antimicrobial, anti-reflective, and self-cleaning functions. In this study, the wing chemicals of two cicada species were examined using the Pegasus® BT 4D GCxGC-TOFMS system and analyzed through the ChromaTOF® software.

Food authentication protects consumers, sellers, and producers from fraud. In this article, scientists discuss new non-destructive methods of food authentication which utilizes LECO Pegasus® BT 4D GCxGC-TOFMS and ChromaTOF® software to enhance cultivar classification.

Classification Regions are a feature LECO's ChromaTOF software. Classification Regions utilize the structured nature of a GCxGC chromatogram to organize related analytes into user-defined groups. LECO Ref. #209-066-013

One of the most-common advantages cited when comparing comprehensive two-dimensional gas chromatography (GCxGC) with conventional one-dimensional gas chromatography (1D-GC) is the increase in detectability observed utilizing GCxGC. This document demonstrates how to utilize the Pegasus BT as the detector. LECO Ref. #209-066-012

Literature for Identification Grading System (IGS), developed from EPA's Non-Targeted Analysis Collaborative Trial (ENTACT). LECO's IGS works with ChromaTOF® software. LECO Ref. #209-284

Reference Library developed by LECO and Dr. Oliver Fiehn (University of California-Davis). Over 1,100 spectra of 700 metabolites available for sample and data comparison of chromatograms. This metabolomics reference library is fully integrated into the ChromaTOF® software suite. LECO Ref. #209-207

Utilizing Gas Chromatography-Olfactometry (GC-O) can help identify active odor compounds in complex mixtures. But, what happens if GC-O does not identify a compound, but an off-flavor or malodor is still present? Ray Marsili (Analytical Flavor Chemist and Owner, Marsili Consulting Group) discuss the process of utilizing ChromaTOF peak deconvolution software to identify hidden compounds.
