Working principle

The gas chromatograph employs a unique separation technology, using gas as the mobile phase to drive the sample to flow through the chromatographic column. During this process, different components in the sample form different migration speeds within the column based on the differences in their partition coefficients between the stationary phase and the mobile phase. This enables efficient separation. The separated components then enter the detector one after another. The detector converts them into electrical signals, which are analyzed and recorded through the data processing system. Eventually, a clear and accurate chromatogram is presented, providing a strong basis for component analysis.

Technical advantages

1.High separation efficiency: Gas chromatographs can efficiently separate numerous components in complex mixtures. Even compounds with similar structures can be easily distinguished, providing a guarantee for accurate analysis.

2.High sensitivity: Equipped with a highly sensitive detector, it can detect trace amounts of substances and meet the analytical requirements for low-concentration samples.

3.Fast analysis speed: Advanced instrument design and optimized analytical methods enable the gas chromatograph to complete one analysis within a short period of time, significantly enhancing work efficiency.

4.Widely applied: Gas chromatographs can be utilized in multiple fields such as petrochemical industry, environmental monitoring, food safety, and medical and health care, for analyzing the components and conducting quality control of various samples.

5.Accuracy is high: Through precise injection control, stable separation conditions and reliable data processing, gas chromatographs can provide accurate and reliable analytical results, offering strong support for decision-making.
