GC112A Gas Chromatograph |
|
| Characteristics |
1. 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. |
| 2. 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. |
| 3. Four paths of independent control sections: column oven, sample injector, detector and thermal conductive pond. |
| 4. 5-ramp programmed temperature rising control. Auto-drop of temperature of column oven (auto-opening the door behind the oven) to a fast cooling. |
| 5. Dual FID provided with options of GC112 A-TCD, GC112A-ECD, GC 112 A-FPD and GC112A-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. |
| 6. 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. |
| 7. Analysis can be conducted in packed or capillary column with multiple sampling methods. |
