Application of Gas Chromatograph:

GC-901 gas chromatograph can realize full EPC electronic flow control, realize full computer control of the instrument, and can be equipped with a high-precision liquid automatic sampler. It can be widely used in many fields such as petroleum, chemical industry, environmental protection, food safety, disease control, education and scientific research, and can analyze the macro, micro and trace amounts of organic matter, inorganic matter and gas.

Gas Chromatograph Feature:

1. Color widescreen, unique design of touch keys

  • 7-inch industrial color LCD screen design, more complete display information, more reasonable interface operation

  • Two sets of operating systems in Chinese and English to meet different user needs

  • Adopting resistive touch screen, feel good, durable, double operation of screen and software to achieve seamless connection

2. Humanized software operating system

  • Adopting advanced 10/100M self-adaptive Ethernet communication interface, built-in IP protocol stack, easily form a local area network, realize long-distance transmission, remote control, and remote diagnosis.

  • Equipped with IBrainChrom workstation, which can support multiple chromatographs (253 sets) to work at the same time, realize data processing and reverse control.

  • Having complete audit trail, user rights management, electronic signature and other functions, so that data and documents meet GMP management requirements

  • The built-in Modbus/TCP server of IBrainChrom workstation can easily connect the analysis results to DCS (distributed control system)

  • 3 independent connection threads that can be connected to local, laboratory supervisors and authorities, allowing them to monitor the operation of the instrument and analyze the data in real time.

3. High-precision gas flow control system (EPC)

  • High-precision gas flow control, to ensure the accuracy of GC analysis, to ensure the efficiency of daily analysis, EPC control accuracy 0.01psi

  • It realizes the self-protection of gas circuit failure, automatic ignition, re-ignition, automatic opening of the gas circuit, and one-key start.

  • A variety of control combination modes of operation, automatic pressure and flow adjustment, control and display, can operate in gas-saving mode

4. Leading structural design

  • Modular structure design, easy to upgrade, can be equipped with a variety of high-performance detectors such as FID, TCD, ECD, FPD and NPD, etc., to meet the analysis needs of complex samples

  • Advanced sampler design, unique liner structure and special processing technology to ensure zero adsorption of samples

  • Adapting to a variety of sample injection methods such as: headspace sampler, thermal desorption analyzer, liquid automatic sampler, easily competent for the analysis of various sample types

  • Timed self-starting program can easily complete the laboratory online analysis of gas and liquid samples
