GC-7800 is a classical gas chromatograph instrument which integrates the most advanced chromatography technique and national or international standards with the most extensive applications by the experienced experts of Labthink.

It can be wildly used to test the relative indexes of various materials, gases, smell, residue, and cigarette packages, because of its powerful functions and high sensitivity.

This instrument becomes the best choice for gas chromatographic analysis and control of testing organizations, research institutions, packaging companies as well as food and medical industries.

Characteristics:

• Instrument utilizes patent design of solvent residue test, and is available for the determination of solvent purity and water content of hydrophilic solvents.
• This instrument supports the organic compound determination of packing paper for cigarette boxes and label paper.
• Controlled by micro-computer with high integrated circuit design and high performance.
• Test specifications are displayed in very clear way by LCD.
• Full keyboard setting for temperature and detector parameters.
• Two test modes of constant temperature and temperature program are available with high accuracy and less time consuming.
• Linear temperature program with 5 orders (customization available).
• Modular designed detector provides more choices for convenient replacement.
• Practical design of base line auto-zero, power failure protection, and test data storage or inquiry ensures the safe operation condition.
• Supported by professional chromatography data system with powerful processing functions.
• The instrument is controlled by micro-computer and integrated circuit, with Chinese operating interface and big display screen. Functions of keyboard inputting parameters, power failure protection and file storage or inquiry provide a comfortable operating environment.
• Reliable and flexible gas path system is easy to be extended with dual column and dual gas path operation, which is available for different feeding gases or tests and selected in accordance with user analysis requirements.
• Detectors uses unitized combination design and plug-and-play (PNP) extension control mode. Instrument is equipped with hydrogen flame ionization detector (FID) and thermal conductivity detector (TCD). Four different detectors could be installed simultaneously at most in accordance with user analysis requirements.
• Constant temperature or temperature program can be achieved in this instrument. And preset temperature of chromatographic column chamber could be reached through automatic open-close of its flexible back door.
• Sampler system is equipped with packed column, capillary column and other devices to transfer test gases into the system.
• Instrument is designed with functions of lower pressure for carrier gas tube and protection for gas transmission interrupt.
• High temperature protection is applied so that instrument could stop working and alarm when the temperature of any gas tube exceeds the preset temperature (set at 20°C).
• 1500mv wide range of response signal, with good consistency, could meet analysis requirements of high purity samples.
• Good performance of chromatographic column box makes it possible to achieve the operation at room temperature +3°C, even when the temperatures of detection and vaporizing chambers are as high as 200°C. Instrument comes with good repeatability of temperature program to ensure the retention time consistency of sample components.
• Special designed operating software and hardware could automatically monitor the whole operating process, which creates a safe test environment for users.
• Instrument could be easily connected with chromatography data converter, data system or other graphing devices.
• Professional chromatographic data system provides powerful and intelligent data process function to automatically identify the names and quantities (mg/m2) of residual solvents of tested samples in accordance with reference data. Instrument is also available for the detection of solvent purity and water content of hydrophilic solvents.
