Gas Chromatograph
Product Code : GC 2979 Plus
Gas Chromatograph
Characteristics
- Brand-new designed microcomputer temperature control system of world advanced control technology. High accuracy of temperature control (optimum: +0.05oC), high reliability and anti-interference
- Control and operating parameters (including for detectors) set up by keyboard. Self-diagnosis system, power-full 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
- 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
- Advanced functions: Auto On/Off temperature control system, permanent data storage, file storage and call and over-temperature protection
- 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.
