Gas chromatography (GC)

Gas chromatography (GC) is an analytical technique used in surface technology to examine the composition of gas mixtures. This method enables the precise separation and identification of individual gas phase components. In surface technology, gas chromatography is often used to analyze the composition of gases produced during various surface treatment processes.

During gas chromatography, the gas mixture is passed through a column containing special stationary phases. The interactions between the individual gas components and the stationary phase lead to different retention times. These retention times are recorded by detectors and converted into chromatographic peaks. The analysis of these peaks enables the precise identification and quantification of the individual gas components.

In surface technology, gas chromatography is used to evaluate the effectiveness of surface treatment processes. By analyzing the gases produced during these processes, researchers and engineers can gain important information about the process and the efficiency of the treatment. This is particularly relevant for galvanic processes, coatings or other surface modifications.

In addition, gas chromatography in surface technology enables the identification of by-products or unwanted chemical reactions that may occur during surface treatment. This helps to improve the quality of treated surfaces and make processes more efficient.

Overall, gas chromatography as an analytical technique in surface technology offers a precise method for gaining insights into the chemical processes during surface treatment and thus optimizing the quality and efficiency of these processes.
