What this instrument is designed to do, in plain terms.
- Gas Chromatography GC-7860 series
- The GC fully absorbs advanced technology from similar foreign products and adopts industry-leading manufacturing technology and processes, ensuring the reliability and trouble-free operation time of the instrument. It can not only maximize normal operation time and reduce maintenance times, but also be more concise and reasonable in structure, with a more macroscopic and atmospheric appearance; Clear keyboard operation and convenient system control software make it easy to learn and operate. The GC system can be loaded with advanced electronic gas path control (EPC) systems, providing industry-leading excellent quality and reliable results for industry users. The GC has unique network remote transmission and control functions, making it a reality for unmanned, decentralized monitoring, and centralized control of the instrument; The data analysis results can be connected to DCS to complete the statistics, analysis, and monitoring of chromatographic component content, thereby improving the automation of the production process.
- All injection port and detector gas paths can be controlled by an electronic gas circuit (EPC) to provide better retention time and peak area accuracy. The users can set various parameters such as gas flow rate, external events, temperature, and detector through anti control software, and save all parameters of the analysis method. The digital circuit ensures consistent settings between different operators during each operation. Therefore, users can achieve better retention time reproducibility and more consistent and reliable results, achieving twice the result with half the effort.
