GC6891N Gas Chromatography for Petrochemical

·Product discription
GC6891N is a new generation of high-end laboratory GC,which is produced according to the national standards. Based on the most advanced international technical area and application experience, its features, reliability and sensitive application are in the world high level.

1. Injector flow, column carrier flow, detector gas flow are controlled by EPC.

1.1 Micro-channel gas integrated board
1.2 Imported micro-ratio and flow/pressure sensor
1.3Temperature self-compensation to ensure the accurate flow, its pressure controlling can precise to 0.01Psi.
2. Industry-leading detector design.
2.1 All the detectors with high-precision electronic flow/pressure control.
2.2 It can be matched with packed column and capillary column.
2.3 The amplified board after special ceramics treatment can keep stable in wet season.
3. It is safe and reliable with the functions of self-ignition and hydrogen leakage self-protection.  
4 Accurate tracking design for furnace temperature.

5 Accurate programmed heating control for the furnace temperature.
5.1 Inner temperature controlling precision: <0.01
5.2 Temperature between inner points: ≤1ºC
5.3 Quick heating and cooling, the max programmed heating speed: 120ºC/min, balance time: 10 sec, cooling time: 300ºC-50ºC for 6 minutes.
5.4 The temperature precision is absolutely controlled(compared with the real temperature, the difference is less than 0.3ºC).
6 The achievement of gas circuit cutting technology 
6.1 Complex samples separation can be analyzed by multidimensional chromatography.
6.2 It saves the analysis time and period by blowback function of the chromatograph column.
7 Chromatographic columns can be heated individually, and the using temperature can be set according to the different columns, so that make every column separately. 
8 GC6891N adopts the advanced power distribution management shunt. One 3000-watt UPS can provide stable working power for 10 sets of GC with the normal power of 2250w/set.
9 GC6891N adopts the imported valve configuration system, which can carry 8 valves (4-way valve, 6-way valve, 10-way valve or liquid sampling valve) to automatically control and operate by sequence. 
10 GC6891N uses 8-digit auto-injectors (you can choose Agilent 7683/7693 liquid auto-injector).
