Gas Chromatography GC6000

GC6000

Product Description

Gas chromatography is the detection and analysis of gaseous substances or substances that can be converted into gas at a certain temperature. Due to the different physical properties of the substances, the distribution coefficients of each component in the sample between the gas phase and the stationary liquid phase are different. When the vaporized sample is carried by the carrier gas into the chromatographic column for operation, the components are in two of them. Repeated distribution between the phases. Due to the different adsorption or dissolution abilities of the components of the stationary phase, although the flow rate of the carrier gas is the same, the running speeds of the components in the chromatographic column are different. After a certain period of flow, they are separated from each other. Leave the chromatographic column in order and enter the detector. After the signal is amplified, the chromatographic peaks of each component are depicted on the recorder. According to the peak position, determine the name of the component, and determine the concentration according to the peak area. This is the working principle of a gas chromatography.

Technical characteristics of gas chromatography

High automation and high efficiency

  • The whole machine realizes computer control;

  • Rich self-diagnosis and alarm functions;

  • Multi-step program temperature rise to meet the various needs of users. The door opening mechanism after the oven is controlled by a computer can realize rapid automatic program heating and rapid automatic cooling.Greatly improve work efficiency.

Easy to operate

  • Very low noise, FID noise is better than the international leading level;

  • High sensitivity detector, low baseline drift;

  • Good reproducibility of peak area and retention time;

  • With high temperature control accuracy and good stability, the column thermostat provides a constant temperature environment for the effective separation and detection of various components.
