C-7890 gas chromatograph performance characteristics Main performance characteristics
Main performance characteristics:
1.Large scre en in both Chinese and English display, screen switching simple and clear, stylish appearance.
2.After the door "smart door controller" technology (patent number: ZL 2012 2 0286920.0).
3.Perfect self-diagnosis function, can be convenient to check the fault location and fault type.
4. Perfect temperature overheating protection and platinum wire resistance open circuit, short circuit alarm function, to ensure that the temperature is not out of control.
5.Optional built-in AD conversion circuit, direct output digital signal.
6.According to user needs can achieve reverse control function, all parameter settings and analysis control can be completed on the PC.
7.In the condition of dry ice or liquid nitrogen, can achieve negative temperature operation, support - 80 °C to 450 °C wide range of temperature control
8. Within 180 °C, column box control accuracy up to ± 0.01 °C. 9. Can be installed at the same time two filling column a capillary column or installed at the same time two pay capillary column,
9.Can achieve double thermal conductivity, double FID, or thermal conductivity and hydrogen flame at the same time.
10.Can be installed at the same time three detectors and methane converter.
11. With automatic sampling function (patent number: ZL 2012 2 0285852.6).
12. The instrument has the function of gas cut-off automatic power off protection (patent number: ZL 2012 2 0285835.2).
13. Six temperature control, eight step program heating, capillary and filling column vaporization chamber independent temperature control, intelligent double after the door.
14. The instrument uses 5.7 inch color screen display, according to the need to upgrade the display of two spectrum at the same time; with automatic flow display function.
15. Can support the use of headspace sampler, thermal analyzer, liquid automatic sampler, gas automatic injection valve and other external equipment.
16. With automatic ignition function (patent number: ZL 2012 2 0285854.5)
Main technical indicators:
