To Run or to Fly: A Comparison Between HPLC and GC

Many chemical compounds, including drugs and metabolites, can be analyzed by either gas chromatography (GC) or high-performance liquid chromatography (HPLC). Because both techniques function under the same basic principles of compound separation, identification, and quantification, it can sometimes be tricky to choose one over the other. But knowing what differentiates HPLC and GC can definitely […]

How Separation Works in Column Chromatography Methods

Separation in column chromatography relies on differences. Molecules vary in size, charge, polarity, and solubility. We leverage these differences to distribute molecules between a stationary phase and a mobile phase. But because molecules are so different, it’s not possible to have a single method that works for all. In my previous article I discussed the […]

The Basics of Running a Chromatography Column

Column chromatography is a common technique used to separate individual compounds from a mixture. You can use column chromatography on both a small or large scale to isolate and purify material for use on a later experiment. If you are new to column chromatography or just want a refresher, then read on for a quick […]

Carrying You Through Gas Chromatography

Maybe you found a paper in which they used gas chromatography (GC) to analyze a sample that is similar to yours and now you are wondering if you should try it too. If you are hesitant because you know little about GC, then this article will help you with that. You may already know that […]
