Product Description
Product Introduction
The GC-210 networked gas chromatograph is an economical, fully digitally controlled gas chromatograph launched by our company. It not only maximizes uptime and reduces maintenance frequency, but also features a simpler, more rational structure, making it easy to learn and operate.
The GC-210 gas chromatograph uses a traditional manual gas path control method, with a more rational layout of the gas path and circuit structure, facilitating operation and daily maintenance. Simultaneously, the instrument also features unique network remote transmission and control capabilities, enabling unattended operation, decentralized monitoring, and centralized control. Data analysis results can be connected to a DCS (Distributed Control System) to complete the statistical analysis and monitoring of chromatographic component content, improving the automation of the production process.
Applications and Detection Indicators
The GC-210 gas chromatograph is widely used in various analytical fields, including petrochemicals, fine chemicals, biopharmaceuticals, environmental protection, food hygiene, high-purity gases, power generation, brewing, scientific research, and education.
General-Purpose Gas Chromatograph Performance Characteristics
1. Large-screen dot-matrix Chinese LCD display (color touchscreen optional), supporting Chinese/English switching.
2. Networked communication (using Ethernet interface IEEE802.3), full computer-controlled operation.
3. Manual gas path control: Employs dual precision valve manual control with pressure stabilization followed by flow stabilization.
4. Pressure and flow display methods: Pressure gauge pointer display, digital flow reading.
5. Diverse injection systems: packed column injection, capillary split/splitless injection, valve injection, automatic liquid injection (supporting up to 150 sample vials), fully automatic headspace injection, pyrolysis injection, thermal desorption injection, and purge-and-trap injection are all available.
6. A wide range of detector types: up to two detectors can be installed, including TCD, HTCD, uTCD, FID, FPD, ECD, NPD, ZD, PDHID, PID, and AID.
7. Unique network remote transmission and control capabilities, enabling unattended analysis, distributed monitoring, and centralized control.
8. Data can be integrated into a DCS system for statistical analysis, monitoring, and control of chromatographic components, improving the automation level of production process control.
