Product Details

advanced Gas Chromatograph analyzer GC-7900

GC7900 is the latest model of gas chromatograph developed by Toption, with compact design and outstanding performance.

• 7900 has 9-step temperature program, with maximum heating rate up to 39 °C per minute.

• Three injection ports and three detectors can be mounted at the same time.

• Large LCD screen displays all operating conditions and detection signals.

• Built-in data acquisition board to control 7900 gas chromatography and perform data analysis by PC through RS232 interface.

• Gas pressure is controlled and regulated by the latest advanced technology to ensure accuracy down to 0.1psi.

• Choice of injection port - Packed column, split/ splitless capillary and wide bore capillary column adaptor.

• Choice of detector - FID, TCD, ECD, NPD, FPD.

• D -7900 PC software is a standard with the main unit. The software can perform instrument control, data acquisition, chromatogram manipulation, data analysis and calculation as well as custom reporting.

• Injections can be automated by optional liquid autosampler.

Feature of GC-7900 gas chromatograph analyzer:

1.Fast, stable and efficient column temperature box

The maximum heating rate: 40 DEG /min (less than 200 DEG C).
5 C temperature control, temperature control range, meet the needs of various applications.
With the function of temperature of 9 programme

2. 3 sample inlet ports

Control of the back pressure valve to control the flow of the sample, to ensure the stability of the column pressure, improve the stability of the capillary system.
the separation of the diaphragm cleaning / no diversion into the sample, effectively prevent the emergence of ghost peaks.
The analysis of the packed column and the large diameter capillary column.

3.At the same time, 7 detectors are installed, and the 3 detector can be selected.

Users can be based on the analysis of the requirements, while the installation of 3 detectors, 7 kinds of detector.
FID, TCD, ECD, FPD, NPD, PID, micro TCD 7 detector.
With 3 analog signal output, 1 digital output port

4.Touch keyboard operation, super LCD display

Clear instrument working state.
Can simultaneously display the real-time chromatogram of two detectors.
Keyboard setting instrument operating parameters.
