Gas Chromatograph

Instrument Introduction:

The GC-7960A gas chromatograph is a new high-performance gas chromatograph designed through long-term research and experimentation on the basis of the original gas chromatograph. Using a large number of imported components for production and manufacturing, it has the advantages of good stability and reliability, stable gas flow path, simple structural design, beautiful appearance design, complete supporting facilities, and long service life.

Features

1. 5.7-inch LCD display screen (touchscreen optional), with a user-friendly design interface and one-button operation.

2. Specially developed and designed split flow capillary injection system ensures the stability and accuracy of sample preparation; At the same time, it improves the service life of the chromatographic column and reduces the user's usage cost.

3. Data power-off protection function, the operating data set by the instrument can be saved for a long time after power failure.

4. Self diagnostic fault function: When the set parameters are different from the actual parameters, the instrument will stop running and report the fault on the display.

5. Four types of detectors can be installed simultaneously, with independent circuit systems and signal output terminals.

6. Large volume column box, capable of installing four chromatography columns simultaneously.

7. The specially developed high-sensitivity detector and the integrated design of the electrostatic meter and ignition device have improved the sensitivity and anti-interference ability of the instrument, and will not cause damage to the amplification circuit system due to ignition.

8. The large English screen displays instrument parameters intuitively, greatly facilitating user settings including temperature, pressure, flow rate, range, detector, bridge flow, and other parameters; Intuitive operation includes functions such as switching bridge current, opening and closing temperature control, opening and closing stroke lift, and various time events.

9. The instrument computer is connected to the Internet and can be connected to the instrument through a remote computer to realize remote data collection and management. Improved the degree of freedom of the device and promoted its effective application in the laboratory.

10. The main control circuit adopts advanced dual microprocessors and large capacity memory, making data storage more reliable. The integrated design of the circuit board improves the anti-interference and reliability of the instrument.

11. Using high-precision temperature control circuits, the temperature accuracy of the controlled objects in each heating zone reaches 0.1 degrees.

12. The main box is equipped with an automatic rear door temperature control system, which improves the temperature control accuracy and cooling speed.

13. Multi stage program heating, suitable for the analysis of complex samples with wide boiling points, can be increased to 21 stages.

14. Unit type integral structure design, convenient installation and maintenance.

15. Fully automatic adjustable automatic ignition, no need to press the ignition button to achieve true automatic ignition, and the ignition time and duration can be set arbitrarily. Using alloy materials with an extremely long service life to ensure stability and longevity during use. In the past, old-fashioned ignition still required manual pressing of the keyboard to ignite, and the ignition time could not be set, which had a significant impact on the ignition interval and the lifespan of the ignition device, and also increased maintenance costs for users.
