When you’re working with Gas Chromatography (GC), one of the most critical steps is getting the sample into the GC. You might already understand gas flow paths and general instrument operation—but none of that matters if your sample isn’t prepared correctly. So,...
When you’re running a Gas Chromatograph (GC), one of the most important steps is getting the sample into the instrument. In a previous video, I talked about common autosamplers—like using 2 mL vials with a liquid autosampler, or 20 mL vials for headspace...
Running into a “vial out of range” error on your Agilent GC or GC-MS system? Don’t worry—it’s a common mistake with an easy fix. In this video, we walk through what causes this error and how to solve it, especially if you’re using an Agilent 7683...
Understanding THC Potency Measurement In the cannabis world, the active ingredient is Delta-9 tetrahydrocannabinol (Delta-9 THC). Measuring potency typically means determining how much THC is in the sample. Chromatographic Separation of THC Chromatographically, THC...
Column Flow, Purge Flow, and Split Ratio all relate to the movement and control of gas flow within a gas chromatograph (GC) injector system. Column Flow, Purge Flow, and Split Ratio are essential for sample introduction and separation efficiency. Here’s what they have...
