Compressed air for gas chromatography

Compressed air for gas chromatography in the laboratory

Successful analyses - with clean and dry compressed air

The use of a gas generator is required in laboratories for the on-site production of gases. Since the requirements for compressed air for laboratory applications are very high, for example, it must be extremely clean and dry, it requires oil-free compressed air. Dürr Technik offers the SICOLAB series oil-free compressors, which are especially designed for laboratories.

What is gas chromatography and how does it work?

It is an analytical method to separate, identify and quantify the individual components in the gas mixture.

In gas chromatography, a carrier gas is added to the gas to be analyzed in the laboratory. This carrier gas is often nitrogen, produced by an on-site nitrogen generator using compressed air. The mixture is then injected into the separation column and detected at its outlet. Depending on the strength of the interaction with the stationary phase, the molecules reach the detector sooner or later.

Compressed air for nitrogen generators in gas chromatography

For gas chromatography and LC-MS protein analysis, Dürr Technik’s soundproof, oil-free laboratory compressor, the SICOLAB has proved its worth as the local compressed air supply of nitrogen generators. Clean and dry compressed air is essential for this application. Thanks to the integrated membrane drying system, these laboratory compressor systems meet this important criteria.

Quiet and innovative: Our SICOLAB series “point-of-use”, oil-free laboratory compressors that are made suitable for gas chromatography

The SICOLAB series “point-of-use”, oil-free laboratory compressors utilize an innovative and patented membrane drying system to produce dry compressed air. The system meets the requirements of the ISO 8573-1 standard for compressed air quality, up to class 1:3:1. They operate extremely silently due to a low sound pressure level. The SICOLAB is also easy and intuitive to use, can operate in 100% continuous running mode and therefore perfect for use in gas chromatography applications.

"We use the SICOLAB sound proofed compressor system in our laboratory for inverse gas chromatography. The materials are characterized down to a molecular level. Since the unit is located directly at the technicians' bench, the noise level was very important for us. The SICOLAB compressor system convinced us as the best solution for us."
