sell GC112A Gas Chromatograph

Description

Features

1. The gas chromatograph offers high accuracy of temperature control (optimum: ± 0.*5°C), high reliability and anti-interference.
2. Control and operating parameters, including for detectors, can be set up by the keyboard. Settings include elf-diagnosis system, power-fail protection, file storage and load, and limited temperature. The gas chromatograph uses accurate display of setting and actual value of temperature control of each path, bridge current of TCD, sensitivity of FID, retention and analysis time.
3. It offers four paths of independent control sections, including column oven, sample injector, detector and thermal conductive pond.
4. It has *-ramp programmed temperature rising control and auto-drop of temperature of column oven to a fast cooling.
5. Dual FID provided with options of GC**2 A-TCD, GC **2 A-FPD and GC**2A-NPD, gas sampling valve, transformation oven, absorber and pyrolysis absorber are available for selection. Two detectors can be installed at the same time with high sensitivity. It takes a short time to be stabilized, it is easy to clean and install nozzle.
6. A packed column and capillary column (0.*3 large diameter or small diameter) can be easily installed including a complete set of split sampling connector and tailing connector to be installed free of charge. An optional 0.*3mm large diameter capillary direct sampler is available for choice.
7. Analysis can be conducted in packed or capillary column with multiple sampling methods.
8. A packed column can finish on-column sampling, instantaneous vaporized sampling and gas sampling.
9. The gas chromatograph uses capillary column, which can support split sampling and 0.*3mm large diameter capillary direct sampling.
*0. 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 repeatability and stability of the gas chromatograph.
*1. The gas chromatograph supports an auto ON/OFF temperature control system, permanent data storage, file storage and call and over-temperature protection.
*2. The large capacity column oven (**0x**0x**0mm) can hold capillary column and dual packed column. Built-in heating filament structure is in favor of quartz capillary analysis.
*3. 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 the supply-air system prepared by users.
