GC-7860 Series Gas Chromatograph

 

GC-7860 A/SA gas chromatography use electronic gas circuit EPC/EFC control mode, 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.

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.
 

Features:

• 5.7-inch dot-matrix LCD large liquid display, support Chinese and English switch.
