A gas chromatograph is a laboratory instrument used to study various compounds and separate them into individual components. The analysis provides data on both quantitative and qualitative characteristics. Modern models can detect substances even at minimal concentrations. Thanks to automatic sample injection and analysis control systems, the operator’s work is simplified, and the risk of errors is minimized. When combined with different types of detectors, the device can be easily adapted to specific tasks. Laboratory chromatographs are widely used in production processes across medicine, pharmaceuticals, forensics, and other fields.
Gas chromatographs, regardless of their price, separate a mixture into components through interaction with a carrier and a mobile phase. The gas passes through a special column filled with a sorbent. The device has a complex system that includes the following main components:
Eluent source — carrier gas. Most often, it is a cylinder with liquefied or compressed gas under pressure.
Eluent flow regulator — controls gas consumption and ensures the required pressure at the beginning of the system.
Injection device — feeds the sample into the column.
Column — special tubes filled with a stationary phase to differentiate the mixture.
Detectors — register the concentration of components at the outlet of the system and determine their properties.
Amplifier — amplifies the electrical signal.
The gas chromatograph is also equipped with a flow meter and a recorder to generate a chromatogram. Most devices use a computer, sometimes a recorder.
Buying a gas chromatograph from a leading manufacturer means getting high-quality equipment for highly efficient and controlled analyses. The main advantages of the devices are:
high resolution;
analysis of mixture components;
wide range of substances;
fast separation;
increased sensitivity;
versatility.
Thanks to highly efficient columns, chromatographs are capable of separating even components with similar chemical properties. Systems for laboratory research are complemented by software for controlling the analysis, processing, and interpretation of indicators.
