Gas Chromatograph GC-8850

Features
1. It adopts a technologically advanced 100M/Gigabit Ethernet communication interface and a built-in IP protocol stack, so that the instrument can achieve long-distance data transmission through the internal LAN and the Internet of the enterprise; it facilitates laboratory setting, simplifies laboratory configuration, and facilitates data analysis management.
2. Three independent connection IP addresses are designed inside the instrument, which can be connected to a working computer (laboratory site), a computer in charge (such as the quality inspection department, production department, etc.), and senior management computers (such as the Environmental Protection Bureau, the Technical Supervision Bureau, etc.), and can monitor the operation of the instrument and data results in real time when needed.
3. The dedicated workstation equipped with the instrument can support multiple chromatographs at the same time, realize data processing and reverse instrument control, and simplify document management.
4. The instrument can be connected to the chromatography manufacturer through the Internet to achieve remote diagnosis, remote update, etc. (user settings are required).
5. The 7-inch color LCD touch screen equipped with the instrument supports hot plug and can be used as a handheld controller.
6. The instrument adopts a multi-processor parallel working method to make the instrument more stable and reliable; it can be equipped with a variety of high-performance detectors, such as FID, TCD, ECD, FPD and NPD, and up to three detectors can be installed at the same time to meet the analysis needs of complex samples.
7. The instrument adopts a modular structural design, making it simple and convenient to maintain in the later stage. The FID detector has automatic ignition function.
8. The new microcomputer temperature control system has high temperature control accuracy, excellent reliability and anti-interference performance; it has eight completely independent temperature control outputs, which can achieve 16th-order program heating; it has an automatic rear door opening system for column boxes, and the near-room temperature control capability is improved, and the speed of rising/reducing is faster. Each heating control unit has an overtemperature protection function.
9. The instrument carrier gas is equipped with advanced electronic flow control unit (EFC) and electronic pressure control unit (EPC), which realizes digital control of the gas flow path, greatly improving the stability of the instrument and the reproducibility of the analysis results; retention time repeatability: Dt≤1%min (absolute deviation); peak area repeatability: RSD≤1.5%.
10. The chromatograph has a built-in low-noise, high-resolution 24-bit AD circuit and has the functions of baseline storage and baseline deduction.
11. The standard anti-control chromatography workstation is suitable for operating systems such as WinXP, Win2000, Win7, Win8, Win10, etc.
12. A chromatographic microcomputer system with completely independent intellectual property rights has the standard MODBUS/TCP protocol and can be connected to the DCS system.
