GC9160 Gas Chromatograph

GC9160 gas chromatograph  

Introduction:

GC9160 multi function gas chromatograph is the latest model of gas chromatograph. It adopts the latest information technology, in the temperature control, electronic communication circuit, instrument fault self-examination and data power-off protection were unique. The instrument for enterprises, universities, factories and mines, and other instruments uninterrupted use of the characteristics of, and puts forward the design idea of "stability above all else" instrument in the circuit and gas circuit strictly by famous foreign gas chromatograph manufacturer production process control, make it both in stability and sensitivity index are one upmanship, especially in the gas phase chromatograph program heating analysis has great advantages, greatly avoids in the temperature programmed process caused by the baseline drift of quantitative uncertainty factors. The instrument can be applied to a variety of gas chromatography users.

Features:

Control of microcomputer, full keyboard operation, large screen LCD graphic display of Chinese characters, with a blue backlight adopts full Chinese menu input, directly display five road temperature control of the set value, actual value and overtemperature protection value, temperature programmed curve, detector set data, stopwatch and detector output signal curve (mv), a new electronic digital flow display quality.

Microcomputer control, temperature control precision is high, oven has five order temperature programmed.

High precision control valve gas path parts, using the calibration control flow (direct reading type).

And all kinds of chemical workstation, various types of chromatographic data processor, recorder, etc.
