LHYQ

GC9890E (Upgrad Type Gas Chromatograph)

*  Main Points
1. Friendly interfacing gives easy operation.
2. Split / Splitless injection selection.
3. Self-testing function, quickly to find hardware faults.
4. Wide temperature setting: environ + 5 to 450℃.
5. Auto safety shutdown to fully protect detectors and columns.
6. Column compensation to remove baseline drift.
7. Can be expanded to five detector.
8. High-precision EPC (Electronic Pressure Control).
9. Cryogenic oven interface, and may have as low as -80℃ possible.
*  Oven
1. Temperature: environ + 5℃ to 450℃.
2. Programmable three ramp, rate 1 --> 50℃/min；increment: 0.1℃/min, temperature precision: ±0.015℃.
3. User may calibrate oven temperature sensor, and set maximum temp point.
4. Smart backdoor makes it possible to quickly get to set point. It will take less than 12min to drop from 300℃ to 50℃.
*  Injector
1. Packed Column Injection
2. Capillary Column Injection
3. Wide selection for injection systems like Headspace, Thermal Desorber or auto sampler.
