Characteristics of network return control gas chromatograph:

• Using the advanced 10/100m adaptive Ethernet communication interface and built-in IP protocol stack, the instrument can easily realize long-distance data transmission through Intranet and Internet of enterprises;It facilitates the erection of laboratory and simplifies the laboratory configuration and data management.
• Low instrument internal design process of three separate connection, can connect to the local processing, unit director and supervisor, you can easily make unit director and supervisor real-time monitoring instrument is running and analysis data;
• Low instrument equipped with built-in integration design return control chromatography workstation, get rid of the traditional data acquisition card processing, поддержка до 253 sets of chromatographic work at the same time, data processing and the chromatograph, reached the domestic leading level;
• The Modbus/TCP server built in the built-in integrated return control workstation can easily connect the analysis results to the DCS (распределенная система управления), and all parameters of the real-time return control chromatograph;
• The instrument adopts vacuum fluorescence display technology, высокий – 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, такие как ФИД, ТЦД, РДРВ, ФПД и НДП.
• 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, обнаружение давления, расхода, автоматическое зажигание, 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.
