GD122A High Accuracy Gas Chromatography Equipment

GD122A High Accuracy Gas Chromatography Equipment

I.Characteristics

• Brand-new designed microcomputer temperature control system of world advanced control technology. High accuracy of temperature control (optimum: ± 0.05°C), high reliability and anti-interference.
• Control and operating parameters (including for detectors) set up by the keyboard. Self-diagnosis system, power-fail protection, file storage and call, limited temperature setting.
• Accurate display of setting and actual value of temperature control of each path, bridge current of TCD, sensitivity of FID, retention and analysis time.
• Four paths of independent control sections: column oven, sample injector, detector and thermal conductive pond.
• 5-ramp programmed temperature rising control. Auto-drop of temperature of column oven (auto-opening the door behind the oven) to a fast cooling.

• Dual FID provided with options of GD112 A-TCD, GD112A-ECD, GD 112 A-FPD and GD112A-NPD, gas sampling valve, transformation oven, absorber and pyrolysis absorber available for selection.
• Two detectors can be installed at the same time with high sensitivity. Short time to be stabilized and easy to clean and install nozzle.
• Packed column and capillary column (0.53 large diameter or small diameter) can be installed easily including a complete set of split sampling connector and tailing connector to be installed free of charge.
• Optional 0.53mm large diameter capillary direct sampler is available for choice.
• Analysis can be conducted in packed or capillary column with multiple sampling methods.
• Packed column: on-column sampling, instantaneous vaporized sampling and gas sampling.
• Capillary column: split sampling and 0.53mm large diameter capillary direct sampling.
• Construction of dual gas path, dual sample injector and dual packed column system can effectively avoid baseline undulation and drift in real time and facilitate programmed temperature rising analysis.
• Accurate and scaled type gas path control valves will provide a high repeatability and stability.
• Advanced functions: auto ON/OFF temperature control system, permanent data storage, file storage and call and over-temperature protection.
• Large volume column (300x280x270) can hold capillary column and dual packed column. Built-in heating filament structure is in favor of quartz capillary analysis.
• A complete set of accessories including purifier, pressure-reducing valve, gas path tube, wrench and tools, injection needle and connectors of all kinds are provided free of charge and are ready to connect with supply-air system prepared by users.
