Gas Chromatography Advances

Gas chromatography (GC) continues to evolve as one of the most powerful tools in analytical chemistry for separating volatile compounds. Recent advances focus on enhanced column efficiency, miniaturization, fast GC, and the development of more selective detectors. These improvements have significantly reduced analysis time while increasing resolution and accuracy. Innovations in sample introduction, such as headspace analysis, solid-phase microextraction (SPME), and thermal desorption, have enhanced GC’s applicability across environmental monitoring, food safety, petrochemical analysis, and forensic sciences. Moreover, modern GC systems integrated with advanced software enable real-time data acquisition and automation, making them indispensable in both R&D and routine testing environments. The integration of gas chromatography with mass spectrometry (GC-MS) has further widened its application scope by providing qualitative and quantitative data with high sensitivity and specificity. With sustainability gaining importance, low-energy GC systems and green carrier gas alternatives like hydrogen are also gaining attention. This session explores the transformative trends, practical challenges, and future pathways in gas chromatography for both academic and industrial applications.
