Gas Chromatograph

Gas Chromatograph HYGC-1189Introduction
HYGC-1189 network electric chromatograph is designed and manufactured according to the gas chromatograph process and gas chromatography power system recommended by the guidelines of the People's Republic of China national standard GB/T 17623-1998, GB/T 7252-2001. This machine adopts three detector process, a sampling, parallel double columns, a shunt. Compared to other gas chromatographs, this instrument is simpler and more sensitive to detection.

Features
★ Using advanced 10/100M technology adaptive Ethernet communication interface, and a built-in IP protocol stack.
★ Design of 3 independent connection process. The instrument, can be connected to the local processing (Laboratory), and supervisors.
★ Instrument is equipped with a network workstation version that can support multiple chromatographs simultaneously (253).
★ Instrument can be connected to the manufacturers through the Internet, to realize the remote diagnosis, remote program update (user license).
★ The instrument is equipped with a 5.7-inch color LCD screen to meet the needs of different users.
★ System in English, with 2 sets of operating system, which can be switched freely.
★ Adopting a multiprocessor parallel working mode, the instrument is more stable and reliable.
★ The instrument adopts modular structure design, with convenient replacement and upgrade, and protection of investment effectiveness.
★ The microcomputer temperature control system is brand new, with high temperature control accuracy, high reliability and anti-interference performance.
★ Starting from the well-designed time, the instrument can begin to complete the analysis of the gas sample relaxed (to be equipped with automatic sample parts).
★ The instrument adopts a simple and convenient microcomputer keyboard to control the operating system. It also has the design of automatic detector identification technology, fault diagnosis, function power-off data protection and automatic memory setting parameter functions.
★ Chromatography machine built-in low noise, high resolution of 24 bit AD circuit, and has the functions of storage, baseline deduction.
