Product Description

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.
