GC‐7860 series network‐based gas chromatography is a new digital full control gas chromatography. The instrument has fully absorbed the advanced technology of foreign similar products and adopted the leading manufacturing technology to ensure the reliability and trouble‐free operation time of the instrument. It can not only maximize the normal operation time, reduce the number of maintenance, and in the structure of more concise and reasonable, simple to learn, easy to operate.
GC‐7860 gas chromatography gas circuit control has two modes of manual and electronic gas circuit EPC/EFC control, advanced electronic gas circuit control (EPC/EFC) system, can provide industry users with industry‐leading excellent quality and reliable results. The instrument has a unique network remote transmission and control function, so that the instrument in unattended, decentralized detection, centralized control into a reality; Data analysis results can be connected to DCS to complete the statistics, analysis and monitoring of chromatographic component content and improve the automation of the production process.
GC‐7860 series gas chromatography is widely used in petrochemical, fine chemical, biological medicine,
environmental protection, food hygiene, high purity gas, electricity, wine making, scientific research and education and other fields.
All inlet and detector gas paths for the GC‐7860 gas chromatography can be controlled by an electronic gas circuit (EPC/EFC) to provide better retention time and peak area accuracy. Instrument users can set various parameters such as gas flow rate, shunt ratio, external events, automatic sampler, temperature and detector through the reverse control software, and save all parameters of the analysis method. The digital circuit keeps Settings consistent between operators on each run. As a result, users can achieve better retention time reproducibility and more consistent and reliable results.
GC‐7860 series network‐based gas chromatography can be configured with 6‐bit, 15‐bit, and 150‐bit liquid automatic samplers, and each parameter can be controlled by the reverse control software, which will bring better repeatability and improve work efficiency, while eliminating errors caused by manual samplers.
