The GDC-9560B Gas Chromatograph Analyzer is designed to analyze the gas content in insulation oil using gas chromatography. It effectively identifies potential faults in operating equipment such as overheating or discharge, ensuring the safety of the power grid. This device is also essential for manufacturers of gas/oil equipment to test their products before they leave the factory.
In this system, gas acts as a carrier. When the sample gas is introduced into the sample injector, it enters the packed column or capillary column with the carrier gas. Due to differences in boiling point, polarity, and adsorption coefficient among the components of the sample gas, they are separated. The detector then detects each component sequentially based on its physical and chemical properties. Finally, the chromatographic analyzer records and analyzes the chromatogram of each component to provide accurate results.
- 5.7-inch color LCD screen, suitable for different user needs.
- Equipped with an advanced 10/100M adaptive Ethernet communication interface and built-in IP protocol stack, enabling easy long-distance data transmission via intranet or internet.
- Three independent connection processes allow integration with local processing (laboratory), making it easier for supervisors to monitor and analyze results.
- Includes a network edition workstation that supports multiple chromatographs simultaneously, simplifying document management and reducing lab investment and operational costs.
- Supports both English and Chinese language interfaces, allowing users to switch freely.
- Utilizes a multiprocessor parallel working mode, offering stability and reliability for complex sample analysis. FID and TCD detectors are standard; other detectors can be added if needed.
- Includes one TCD detector and two FID detectors. Hâ‚‚ and Oâ‚‚ are detected by the TCD, while hydrocarbons like methane, ethylene, ethane, and acetylene are detected by FID1. CO and COâ‚‚ are detected by FID2.
- Features a new microcomputer temperature control system with high precision and reliability. It has a 6-channel independent temperature control system, 16-step temperature programming, and a broad range of sample analysis capabilities. It also includes an automatic door system to improve low-voltage temperature accuracy and speed.
- Modular design makes system upgrades clear and convenient.
- Includes timing and self-starting programs for online gas sample analysis (users must select the appropriate online sampling components).
- Fully computerized keyboard operation system, simple and convenient. Detectors feature automatic identification technology, along with fault diagnosis and power-off data protection functions, and automatic memory of setting parameters.
- Built-in low-noise, high-resolution 24-bit AD circuit, with baseline storage and deduction functions.
- Compatible with Windows XP, Win2000, and Windows 7 operating systems. Standard CDF files are used for sampling data, allowing integration with Agilent and Waters chromatography workstations.
- Features a MODBUS/TCP standard port for easy integration with DCS systems.
- Can be integrated with automatic samplers from various manufacturers, such as Shimadzu AOC-20i, HTA HT series liquid/gas samplers.
