If you’ve ever left an M&M on a napkin and watched the colored coating split into different dyes – you have a base-level understanding of how chromatography works.

Keep reading to learn all about gas chromatography and the important role that the GC vial plays in this essential process.

Gas chromatography is used in pharmaceuticals, the food industry, vehicle manufacturing, meteorite analysis, environmental safety analysis, crime investigations, and more!

What Is Gas Chromatography?

Gas chromatography, by definition, is an analytical separation technique used to separate volatile gaseous compounds into their components. After isolating the components, they measure the level of absence or presence.

In layman’s terms, it helps scientists identify what small things add up to the big thing. And then measure how much of each small thing is there. Simple, right?

Other forms of chromatography are less sensitive than gas chromatography. They don’t enable scientists to determine the amount of each component present. Gas chromatography is incredibly valuable in a number of industries because of its in-depth and precise readings.

How Does Gas Chromatography Work?

A gas chromatograph is a piece of apparatus that enables you to separate gaseous compounds into their components. It’s useful because the components can be studied and measured afterward.

Different components have their own phase preference. Some prefer the mobile phase and move swiftly during the chromatography process. Others prefer the stationary phase and move slowly. Well, it entirely depends on the severity of the clog and the condition of the pipes. Hydro jetting works as a power-pack. On the other hand, snaking works as the primary method of clearing clogs.  The time it takes for a substance to pass through the chromatography column is known as its retention time.

To perform the analysis, you will inject the substance you wish to analyze into a carrier gas inside your chromatograph’s injection port. The gas is then sent down a column. As it travels through the column, the different components separate according to their phase preferences.

The proceedings of the reaction are recorded on a chromatograph.

Reading a Gas Chromatograph

A gas chromatograph tracks the strength of response (y-axis) against time (x-axis). The number of components in a compound is represented by the number of peaks in the graph. The height of each peak tells you how much of each component is present. The position of the peak shows the substance’s retention time.

Importance of the GC Vial

It’s important to handle volatile substances using the correct apparatus.

Gas chromatography vials are specifically designed to hold unstable substances. They ensure the most accurate results during the chromatography process. Made with reliable, airtight closures, a GC vial keeps your readings accurate and trustworthy.
