The GDC-9560B Gas Chromatograph Analyzer is a high-performance instrument designed to analyze gas content in insulating oil using gas chromatography. It plays a crucial role in identifying potential faults such as overheating or discharge in operating equipment, ensuring the safety and reliability of the power grid. This device is also widely used by manufacturers of gas and oil equipment for quality control before products leave the factory.
The system uses carrier gas to transport the sample into a packed or capillary column. Due to differences in boiling point, polarity, and adsorption coefficient among the components of the sample gas, they are separated within the column. The detector then identifies each component based on its physical and chemical properties. Finally, the chromatographic analyzer records and analyzes the resulting chromatogram to provide accurate results.
- 5.7-inch color LCD screen for enhanced user experience.
- Advanced 10/100M adaptive Ethernet communication interface with built-in IP protocol stack for seamless long-distance data transmission via LAN or internet.
- Three independent connection processes for local processing (laboratory) and remote monitoring, making it easier for supervisors to track and analyze results.
- Equipped with a network edition workstation that supports multiple chromatographs simultaneously, simplifying data management and reducing lab costs.
- Supports both English and Chinese language interfaces for global users.
- Multiprocessor parallel working mode ensures stability and reliability, ideal for complex sample analysis. FID and TCD detectors are standard, with other detectors available upon request.
- Includes one TCD detector and two FID detectors. Hâ‚‚ and Oâ‚‚ are detected by TCD, while hydrocarbons like methane, ethylene, ethane, and acetylene are analyzed by FID1. CO and COâ‚‚ are measured by FID2.
- New microcomputer temperature control system with high precision, 6-channel independent temperature control, 16-step temperature programming, and automatic door system for improved accuracy and faster heating.
- Modular design allows easy upgrades and maintenance.
- Timed and self-starting program for online gas sample analysis (users need to select online sampling components).
- Full computer keyboard operation for ease of use. Detectors feature automatic identification, fault diagnosis, and power-off data protection, with automatic parameter memory.
- Built-in low-noise, high-resolution 24-bit AD circuit with baseline storage and deduction functions.
- Compatible with Windows XP, Windows 2000, and Windows 7 systems. Supports CDF file format for integration with Agilent and Waters chromatography workstations.
- Standard MODBUS/TCP port for easy integration with DCS systems.
- Can be integrated with various automatic samplers, including Shimadzu AOC-20i and HTA HT series liquid/gas samplers.
