Metabolomics Articles

This curated compilation of articles and papers illustrates how Time-of-Flight Mass Spectrometry is advancing metabolomics research. Laboratories around the world use the Pegasus series of mass spectrometers to help their data soar.

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.

Infection from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can lead to severe respiratory tract damage and acute lung injury. Scientists performed untargeted metabolomics analysis using the Pegasus BT 4D GCxGC-TOF-MS on exhaled breath condensate from COVID-19 patients.

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.

In this article from The Analytical Scientist (Issue #90, September 2020), the value of two-dimensional gas chromatography high-resolution time-of-flight mass spectrometry (GCxGC-HRTOFMS) to metabolomics, breathomics, and other -omics fields of study, are examined.
