GC-9803 Gas Chromatograph Introduction
The GC-9803 gas chromatograph has reasonable structure, stable and reliable performance and simple operation. It can be widely used in trace detection of environmental protection, atmosphere, water source and other pollution; analysis, monitoring and research of poisons; biochemistry; clinical application; pathology and virus research; food fermentation; petrochemical; petroleum processing; oil analysis; , prospecting research; organic chemistry; synthetic research; health quarantine; pollution detection analysis and research. The production and scientific research departments, which are used to detect organic solvents, can detect the residual amount of solvent in packaged prints, and can also detect the purity or content of a single solvent.
Executive standard: QBT 2929, GB/T 10004-2008, YBB 00132002 Features
The full-color large 7-inch LCD touch screen electronically displays the flow rate and pressure value of the gas path. Bring better human-computer interaction to users.
The computer counter control and the host touch screen realize synchronous bidirectional control.
Multi-core, 32-bit embedded hardware system ensures reliable operation of the instrument.
One-click start function.
Scalable, synchronized external triggering capability that enables simultaneous startup of the host and workstation by external signals {autosampler, thermal resolver, etc.}.
The extended function interface with 8 external events can be equipped with various air leakage and air-deficiency self-test function control valves, and it can work according to its own set timing.
20 groups of samples tested in memory mode.
RS232 communication port and LAM network port
Various types of imported switching valves (manual, pneumatic or electric control) can be configured for various gas analysis.
High-precision temperature control system with high control accuracy (better than ±0.05°C), the oven has a nine-step program temperature rise;
Air flow manual flow / pressure adjustment, screen display flow / pressure value;
The gas path has air leakage and air shortage alarm function;
It has a complete system self-test function and automatic fault recognition function. Technical parameters
