▏Product Features
The GC3900Pro touch screen gas chromatograph is a high-sensitivity chromatograph product developed and optimized on the bus development platform. With a simple and clear Chinese display interface, it is very easy for beginners
Familiarize the product with clear menus, reasonable layout, real-time display of system parameters through Flash animation, and dynamic display of realistic graphics in a short period of time, so that the instrument is not monotonous
▏Testing Principles
Gas chromatograph is a separation and analysis tool for multi-component mixtures, which uses inert gas as the mobile phase and employs chromatographic column separation technology. When multiple analyses are conductedMaterial entryDuring the chromatographic column, due to various factors
The distribution coefficients of components in the chromatographic column are different, and the flow velocities of each component in the chromatographic column are also different. After a certain column lengthAfterwards, the mixed componentsleaveLeaving the chromatographic column and entering the detector, after detection
Convert into electrical signals and send them to the data processing workstation to complete the analysis of the measured substanceDetection and analysis.
