▏Product Features

The GC3900C touch screen gas chromatograph is a set of highly sensitive chromatograph products that have been improved and optimized on the bus development platform. The simple and clear Chinese display interface is very easy to understand

Scholars have familiarized themselves with the product in a relatively short period of time, with clear order placement, reasonable layout, real-time display of system parameters through Flash animation, and dynamic display of graphics, making the instrument not monotonous.

▏Test Principle

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 componentsDon'tLeaving 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.

▏Test application

Basic Application

natural gas

Refers to all gases that naturally exist in nature，includingAtmospheric circle、Water Circlewait
