• The Modbus/TCP server built in the built-in integrated return control workstation can easily connect the analysis results to the DCS (distributed control system), and all parameters of the real-time return control chromatograph;
• The instrument adopts vacuum fluorescence display technology, high – end atmosphere and convenient interface operation.Have two operating languages in English and Chinese to meet different user needs;
• The instrument adopts the modular structure design, the design is clear, the replacement upgrade is convenient, protects the effectiveness of the investment;It can satisfy complex sample analysis, and it can be selected with many high performance detectors, such as FID, TCD, ECD, FPD and NPD.
• Can realize completely abandoned the traditional mechanical valve, pointer type pressure gauge mode!EPC technology is used to control gas path and improve the automation level of gas chromatography.
• The real gas road failure automatic protection, pressure flow detection automatic ignition, automatic fire extinguishing automatic key, automatic gas path opening, reached a key start;
• When the instrument is designed, it can easily complete the online analysis of the gas and liquid sample (with the sample parts).
• The system is designed for automatic sampler interface, convenient for automatic sampler and future upgrade.
