Gas Chromatography Demystified - Understanding How A GC Works

👉 Want on-demand training on GC and HPLC? Check out Axion Lite, our free online platform with videos, tips, and expert training: https://courses.axionlabs.com/course/axion-lite/#/sales Feeling intimidated by Gas Chromatography (GC)? 🤔 Think it's too complex with all those buttons, gases, and parts? This video breaks down GC operation into easy-to-understand steps! Timestamps 00:00 Video overview 01:12 Understanding gases in GC – helium cylinders 04:04 Understanding gas generators – nitrogen, hydrogen, zero air 09:00 Understanding how gases flow in GC – where gases enter the GC 13:00 Gas flow through the GC 15:10 Where gases exit the GC 17:40 Understanding how samples move through the GC 18:50 Understanding GC autosamplers and injections 29:31 Understanding GC inlets 37:37 Understanding GC columns 41:28 Understanding GC detectors 45:51 Understanding the front panel – 2 troubleshooting buttons Gases: Understand the roles of Helium, Hydrogen, and Air. Learn about high-pressure cylinders vs. safer, economical gas generators (Zero Air, Nitrogen, Hydrogen). Plumbing & Flow Path: Follow the gases from the source, through the plumbing, and into the instrument. See how different detectors (FID, TCD, MS) have different gas needs. The Inlet: Master the MOST crucial part for maintenance! Learn step-by-step how to properly change a septum and liner – solving 80% of common GC problems. Understand manual vs. autosampler injections (including the air gap trick!). The Column: Discover why the column is the "heart" of the GC and get tips on choosing the right one (like the versatile DB5). Detectors: Learn how common detectors like the Flame Ionization Detector (FID) and Thermal Conductivity Detector (TCD) work and when to use them. By the end of this video, you'll understand how a GC works, feel confident performing essential maintenance, and know how to check if your system is running correctly.
