Product details
  • In addition to quantitative and qualitative analysis, gas chromatography can also determine physical and chemical constants such as distribution coefficient, activity coefficient, molecular weight, and specific surface area of the sample on the stationary phase. An instrument for analyzing and detecting the various components in a mixed gas.

    Strictly select top global component suppliers to ensure excellent and stable handling performance of the entire instrument, minimize user side failure rates, and ensure a perfect user experience.
    At the same time, we also provide a series of value-added services for domestic customers, including imported GC modification, maintenance, and customer training.

    Not only is the EPC module standard on the injection port, but it is also standard on various detector units. The fully automatic gas flow control system can comprehensively achieve efficient and intelligent analysis of GC, ensuring the repeatability and stability of gas phase analysis.Flexible and rich hardware expansion performance comprehensively meets the analysis needs of various industries.

  • Having a high-precision and stable gas path control system and advanced detector modules is a guarantee for reliable analysis!
    The laboratory gas chromatograph is equipped with AEFC module as standard, which is installed in all gas control units of the injection port, detector, and auxiliary gas path to ensure perfect GC analysis!
    (1) Microchannel gas path integrated board
    (2) Equipped with imported proportional valve and pressure sensor
    (3) Temperature compensation function ensures the accuracy and stability of flow rate
    (4) Hydrogen leakage protection function
  • Gas chromatography systems can be equipped with various detectors to meet the analysis needs of different fields: hydrogen flame ionization detector, thermal conductivity detector, electron capture detector, flame photometric detector, nitrogen phosphorus detector, photoionization detector, argon ionization detector, and helium ionization detector.
    Hydrogen flame ionization detector (FID)
    1) The signal amplification board has undergone special processing and remains stable in harsh environments
    2) Automatic ignition, hydrogen leakage protection function
    Thermal conductivity detector (TCD)
    1) Suitable for filling columns and capillary columns
    2) Single filament micro pool design, small dead volume, short equilibrium time
    Electron Capture Detector (ECD)
    1) Small volume micro pool design, stable and efficient
    2) Safer and more sensitive, with only 8mCi ultra-low radiation but high response value
    3) Anode blowing effectively avoids cross contamination between samples and has high repeatability
    Flame photometric detector (FPD)
    1) Unique local cooling technology to increase the maximum operating temperature
    2) There is no cold spot for organophosphate pesticides
    3) The internal pipeline is fully inert to ensure zero adsorption of the sample
    Panna Chemlab is a simple software platform specifically designed for this gas chromatograph
    (1) It can quickly set various parameters such as front and rear injection ports, front and rear detectors, column temperature box heating program, chromatographic column conditions, and valve events
    (2) The interface displays real-time data, allowing you to control the status of GC key components at any time
    (3) Double click automatic recognition of chromatographic peak retention time, multispectral comparison and repeatability analysis, advanced data processing, flexible and rich report editing and other powerful application functions meet your various needs for experimental data analysis
