DSH126 Gas Chromatograph

I.Features and performance:

1. The newly designed GC126 microcomputer temperature control system, using the international advanced control technology. High temperature accuracy (better than ± 0.1 ℃) ,reliability .

2. Keyboard settings various control and parameters, the machine has a self-diagnosis, power cut off protection, file storage , limit temperature setting and other functions. 3.8 "large screen accurately displays the various ways of thermostat setpoints, actual values ​​and real-time curve, the detector parameters, the signal value and its real-time curve.

3. With six independent control area: column oven, injector, detector, aids.

4. This product can achieve nine-stage temperature programming, with column oven cooling automatically and open door function , to achieve rapid heating and rapid cooling.

5. The instrument base model is equipped with dual and single high sensitivity hydrogen flame ionization detector (FID), could choose one of the following detector: gas sampling valve, reformer and other accessories, you can also install two kinds of detectors at the same time , the detector with high sensitivity (such as the test result of FID : DFID ≤ 3 × 10-12g / s), short stabilization time, nozzle cleaning and installation is . Technical characteristics:

6. Embedded 32 processors and multi-CPU systems , IT interface technology, temperature parameters set and select detector automatically, the detector operating parameters and the digitization adjust zero automatically function, sensitivity, and polarity digitization set.

7. Fully Chinese menu interface, can display multiple groups parameters, the operation is very simple and convenient.

8. Computer anti-control function, you can operate the instrument through your computer (via USB interface).

9. Needn't external workstation and can provide an analog output interface.
