Episode 64: The Chemistry of Human Decomposition: GC×GC, Body Farms, and Forensic Science

In this episode of  @ChromatographyTalk  [https://studio.youtube.com/channel/UCU9oYSK_peqfuCrwpnv4fqA] David sits down with Dr. Darshil Patel, Assistant Professor of Forensic Science at the University of North Dakota, to discuss his remarkable journey from dentistry in India to becoming a leading researcher in forensic chemistry across Australia, Canada, and the United States.Dr. Patel shares how his work at human taphonomic facilities—commonly known as "body farms"—has helped advance our understanding of human decomposition and the volatile compounds released during the postmortem process. Using comprehensive two-dimensional gas chromatography coupled with time-of-flight mass spectrometry (GC×GC-TOFMS), his research aims to improve human remains detection, cadaver dog training, and the development of future electronic sensing technologies.Topics discussed include:🔬 How a dentist became a forensic scientist🌏 Working in Australia, Canada, and the United States⚰️ What human taphonomic facilities ("body farms") really do🧪 The chemistry of human decomposition📈 Why GC×GC-TOFMS excels at analyzing complex VOC mixtures🐕 How chromatography can improve cadaver dog training🤖 The future of electronic noses and human remains detection🏔️ Challenges posed by geography and environmental conditions🏫 Building a new forensic chemistry laboratory at the University of North Dakota🔍 The future of forensic chromatographyWhether you're interested in forensic science, chromatography, mass spectrometry, or the chemistry behind real-world investigations, this episode offers a fascinating look into one of the most unique applications of analytical chemistry.#ForensicScience #GCxGC #MassSpectrometry #Chromatography #Forensics #GCMS #TOFMS #AnalyticalChemistry #HumanDecomposition #VOCs #UniversityOfNorthDakota #CadaverDogs #BodyFarm #SeparationScience

Episode 63: LC-MS Metabolomics and Next-Generation Ionization Technologies #chromatography #massspectrometry

In this episode of  @ChromatographyTalk  [https://studio.youtube.com/channel/UCU9oYSK_peqfuCrwpnv4fqA], David speaks with Joseph Corstvet from the Fernandez Lab at Georgia Tech about the future of mass spectrometry, LC-MS metabolomics, and the development of low-cost ionization technologies.Joe discusses his work using LC-MS lipidomics to monitor mesenchymal stromal cell (MSC) senescence and explains how metabolomics could eventually become a real-world quality control tool for regenerative medicine and cell therapy manufacturing.The conversation also dives into triboelectric nanogenerators (TENGs) and how these low-cost, modular ionization systems could help make mass spectrometry more portable, accessible, and affordable. Joe explains how TENG-powered electrospray ionization works, why it differs from traditional ESI, and how his group is exploring applications ranging from mass spectrometry imaging to mobile MS platforms.Topics include:• LC-MS metabolomics workflows• Lipidomics and MSC senescence• Biomarker discovery in regenerative medicine• Untargeted metabolomics challenges• TENG ionization technology• Portable and lower-cost mass spectrometry• Mass spectrometry imaging• Ion mobility and future MS trends• ASMS and the future of analytical chemistryIf you enjoy conversations about chromatography, mass spectrometry, metabolomics, and analytical chemistry innovation, be sure to subscribe to Concentrating on Chromatography.#MassSpectrometry #LCMS #Metabolomics #AnalyticalChemistry #Chromatography #Lipidomics #MassSpec #Ionization #ASMS #Biotech

Episode 62: When One Atom Changes Everything | JC Poutsma on Mass Spectrometry, Proteomics & Gas-Phase Chemistry
