2. New digital design, highly integrated electronic circuit, excellent reliability, Chinese keyboard style operation, convenient parameter setting and operation.

3. The column box structure is compact, the layout is reasonable, the temperature is uniform, and the intelligent dual channel rear door design makes the cooling speed faster (from 280 ℃ to 50 ℃ in just 8 minutes), the efficiency is higher, and it can be stably controlled at room temperature of 5 ℃, expanding the application range of the instrument.

4. The instrument can be equipped with two packed column gasification chambers and one capillary gasification chamber simultaneously, as well as two capillary gasification chambers simultaneously, and can be expanded from a single amplifier to a dual amplifier. According to different analysis applications, different combinations can be used to install up to three detectors simultaneously, such as FID, TCD, ECD detectors, etc. Can easily achieve the series and parallel operation of detectors. Truly achieving one machine with multiple uses.

5. The instrument can be equipped with capillary columns of different specifications (caliber 0.2-0.53MM), and its reasonable capillary injection system design (with split/non split injection, diaphragm blowing, and tail blowing systems) makes the out of column effect small and the column efficiency high; To achieve a peak shape with high chromatographic peak height, narrow half peak, and no tailing, thus obtaining accurate and good repeatability quantitative results.

6. The instrument adopts a modular design, making installation simple and maintenance more convenient; The new FID has a lower detection limit and can be easily disassembled and cleaned for the nozzle and ion collection electrode.

7. The gas path adopts a dual design of stabilizing pressure first and then temperature flow; Stable regulation mode, with high precision, high reliability, and convenient and intuitive flow regulation. Equipped with gas/gas leakage protection and prompt function, it can automatically cut off TCD bridge current and protect rhenium tungsten wire from damage.

8. Equipped with a six channel temperature control system, including column chamber, gasification chamber, detection chamber, converter, and external control events.

9. It has a nine order linear program heating function, which can meet the analysis of multi-component samples.

10. It has power-off protection, over temperature protection, and power on self-test functions.
