Gas chromatography (GC) relies on a steady and reliable supply of gases, making gas generators an essential component of a well-functioning GC system. Modern laboratories are increasingly adopting gas generators instead of traditional gas cylinders to enhance...
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...
