GC112A gas chromatograph

Features :
1. High temperature accuracy (better than ± 0.05 ℃) superior reliability and robustness.
2. The product can achieve five stage temperature programming , after the oven has automatic cooling function that is open to achieve rapid cooling .
3. Can be easily installed packed and capillary column ( 0.53 large diameter column or small caliber column ) , and the annex with a full split injection capillary fittings and makeup joints (no extra charge ) 
4.The instrument can be packed column analysis or analysis of capillary columns , can achieve a variety of injection methods .
5. The instrument has a double gas road , twin injectors , dual packed column system structure, can effectively inhibit the baseline fluctuation and drift in real time , suitable for temperature programming analysis .

6. The instrument has an automatic opening and automatic shutdown temperature control systems, data permanently stored , file storage and call , over-temperature protection , and other advanced features.
7. Large capacity oven (300mm × 280mm × 270mm) for easy installation and dual capillary column packed column ; Built-in heating wire structure more conducive to quartz capillary column analysis .
8. Using CAD design technology, mechanical parts and high reliable structure and appearance, very humane.
