Model GC-7860 Network-Based Series - Gas Chromatography (GC)



GC-7860 network-based series Gas Chromatograph Plus, A, B, E, T, N and Micro (portable and onboard series) are available. The instruments fully absorbs advanced technology abroad of the same kind of products, adopts domestic industrial leading manufacturing technology and process, and ensures instrument reliability and non-failure operation time. It maximizes normal operation, reduces maintenance, and makes structure simple, proper, and easy to learn and operate.

It Is extensively used in petroleum and chemical industry, fine chemical engineering, biological pharmaceutical Industry, environmental protection, food health, high purity gas, electricity, wine brewing, scientific research, education and other analyzing.

It has unique remote network transmission and control function and achieved duty-free, decentralized monitoring and centralized control; the data analysis results are input into DCS to finish statistics, analysis, monitoring of the chromatograph group and improve automation of production process.

it is extensively used in petroleum and chemical industry, tine chemical engineering, biological pharmaceutical industry, environmental protection, food health, high purity gas, electricity, wine brewing, scientific research, education and other analyzing fields.

All sample injection port and detector gas circuits of the GC-7860 Plus and B series gas chromatograph are controlled with electronic gas circuit (EPC) to provide better retaining time and peak area precision and provide industrial users with the industrial leading excellent quality and trust results. The instrument user sets gas flow rates, external events, temperatures, detectors, instruments and other parameters with the anti-control software, and saves all parameters of the analyzing approach. Digital circuit makes setting values the same in each operation and by different operators. Therefore, users can obtain better retaining time reoccurrence and more trustable and consistent results, half the work with double results.

The instrument can be configured with automatic liquid sample injector and anti-control software to control parameters, which yield better repeatability and increase operation efficiency, and eliminate errors caused by manual sampling.
