GC1120 gas chromatography is a computerized,high performance,low cost and general purpose gas chromatograph. It have many advantages as high reliability,compact structure and easy to operate. It can be used in very wide fields for QA/QC like trace analysis for environmental protection, atmosphere and water pollution, analysis and research for poison, clinical application, research of pathology and virus, food fermentation, petrochemical industry, petroleum processing, oil analysis, research of geology and prospecting, organic chemistry, synthesis research, health quarantine, etc. The main features of GC1120 gas chromatography are as following:
1) The microcomputer temperature control system with advanced control technology has remarkable performance, which achieve high precision of temperature control (better than ± 0.1ºC), high reliability and strong capability of resisting disturbance. There are 6 separate temperature control zones in the system with the maximal temperature up to 400
ºC. The limit temperature settings and over-temperature protection function guarantee the safety of this instrument.
2) Big screen for display give more information and more easy operation. The curve of program temperature control, baseline can be displayed. And setting and real temperatures of oven, inlet, and detectors can be displayed in one screen.
3) Packed-column injector and capillary split/splitless injector modules can be installed and achieved 4 kinds of injector combinations. Up to 3 injectors can be installed at the same time.
4) Up to three sample injectors can be installed in the instrument at the same time. 6 kinds of detectors can fit with the instrument, including FID, TCD, ECD, FPD, NPD and PID. Each unit can be assembled very easy when requirement.
5) The internal DAQ device for acquiring instrument statues and data is used to carry out real-time control and data handling with one connect cable between instrument and computer. The real control include temperature control for every parts, detector selection and setting, program temperature, temperature's curve display and flow rate display (optional).
6) Data handling include dual channels (can be extended) high speed data acquirement, integral with manual or auto parameters setting, 5 kinds of quantity methods, baseline correction and making report functions.
7) On packed-column injector can be achieved to fit many kind of column. With connecting pieces used, the instrument could complete analysis by wide bore capillary (ID: 0.53mm). Six-way valve is optional.
8) Gas channel have dual stable control system to achieve high precision, high repeatable flow.
Large volume column oven is easy to install one capillary and two packed columns at same time. The oven has the quick heating/cooling function with auto-open back door mechanism. It can achieve accurate control at ambient temperature and 7 stages temperature program.
