Gas chromatography analysis and testing services are essential for separating and analyzing components of complex mixtures based on their physical and chemical properties. Gas chromatography (GC) is widely used in gas chromatography analysis labs for various applications, such as determining the composition of gases, separating complex mixtures, assessing compound purity, and identifying unknown substances.
In a gas chromatography analysis lab, the process involves dissolving a sample in a solvent and vaporizing it. The sample is then distributed between two phases – a stationary phase and a mobile phase – allowing the analytes to be separated effectively. This method is particularly useful for analyzing volatile substances in the gas phase, and it is frequently applied to testing samples like fatty substances that contain small molecular components. Gas chromatography testing services are thus critical for detecting small molecules within larger structures and providing accurate analysis.

A small amount of the analyte (often a dissolved sample) is injected into the gas chromatograph.
The sample is then passed through a long, narrow column usually internally coated with a stationary phase (a solid or a liquid). The column is typically housed in an oven to maintain a constant temperature. This process separates the various compounds within the sample.
An inert gas such as hydrogen is used as the carrier gas in what is called the “mobile phase” as the gas helps move the sample through the column.
As the sample travels through the column, it interacts with the “stationary phase.” Different components in the sample interact differently with the stationary phase based on their molecular weight, boiling point, polarity, and other properties. This interaction causes the components to separate.
Different compounds within the sample are then separated by interacting in the stationary phase and eluting at different times. As the separated components exit the column, they are detected by a detector. The time taken for a component to travel through the column (retention time) is characteristic of that component and is used for identification. Common detectors include flame ionization detectors (FID), thermal conductivity detectors (TCD), electron capture detectors (ECD), and mass spectrometers (MS).
The output of the detector is a chromatogram, which is a graph that shows the intensity of the detected components as a function of time. The area under the peaks in the chromatogram is proportional to the amount of each component in the sample, allowing for quantitative analysis.
Gas chromatography (GC) is a widely used analytical technique across numerous scientific and industrial fields, valued for its versatility and precision in separating and analyzing a broad range of compounds. It is particularly effective for analyzing samples with high levels of organic volatiles. At NJ Labs, we offer gas chromatography analysis services for a variety of applications, including:
