Beijing Natural Gas Gas Chromatography Manufacturer

Natural Gas Gas Chromatograph Performance Features:

1. The instrument features a full microcomputer automatic control system with an adjustable LCD display, providing rich and intuitive content. The Chinese keyboard operation allows for easy parameter setting and operation.

2. Features a new dual-CPU design and original, high-integration Japanese electronic circuit technology, offering excellent reliability and anti-interference capabilities. Temperature control precision reaches 0.1°C, with display accuracy up to 0.01°C, and the power consumption percentage of each heating section can be simultaneously displayed.

3. The three-gas path and large-volume column chamber design allows for the simultaneous installation of three chromatography columns, as well as both FID and TCD detectors. It also facilitates the easy expansion of ECD, FPD, and NPD detectors, along with the addition of gas sampling injectors and reforming furnaces, and other external control equipment.

4. The machine can be easily expanded from a single FID amplifier to a dual FID amplifier, truly achieving the multi-functional use of a single unit.

5. Equipped with two filling column vaporization chambers and an independent capillary tube system. The design of the vaporization chamber draws inspiration from the miniaturization design of similar foreign products, offering rapid heating, no sampling dead zones, and an excellent capillary分流/不分流injection device and tail gas blow system. It allows for easy installation of small-bore capillary columns, large-bore capillary columns, and various filling columns.

6. Equipped with a 5th-order linear programming temperature ramping function, suitable for the analysis of samples with multiple components.

7. The column chamber features a variable frequency intelligent door opening automatic temperature reduction system, with a very fast cooling speed (it takes only 5 minutes to drop from 280℃ to 50℃), achieving near-room temperature operation in its truest sense.

8. Features a six-way independent temperature control system, suitable for multi-way temperature control needs such as installation of conversion furnaces; the column chamber, gasification chamber, hydrogen flame detection room, thermal conductivity detection room, auxiliary 1, and auxiliary 2 all utilize modular design for easier installation and replacement.

9. Features power failure protection, automatically remembers set parameters. Equipped with anti-power surge interference function and stopwatch timing function.

10. Features over-temperature protection, automatically shutting off power and alarming when the temperature exceeds the set limit. If any temperature exceeds the set temperature, the heating will automatically stop; it also provides fault cause prompts and alarm notifications.

11. Features "0℃" protection function. If any temperature display remains at "0℃," the heating will automatically stop to prevent damage to the heating element due to continuous heating in the room. It also provides an alert for the fault cause and an alarm.

12. Our product features an *air cut-off and alarm function, which maximizes protection for the TCD tungsten filament and chromatography column against damage.

13. Wide-range fault self-diagnosis function with 36 types of self-diagnostic information, displaying the cause of the fault and the method of treatment at any time.

14. Stable airway system:

(1) Utilizes a dual-stable design of pressure stabilization followed by flow stabilization for gas flow.

(2) The airway control valves feature high reproducibility and stability.

15. Multiple sample submission methods available:

(1) Filling column head sampling

(2) Filled column gas chromatography injection

(3) Capillary分流/Non-divert injection: Back pressure valve control technology, linear diversion;

(4) Six-way valve gas sampling

(5) Automated Headspace Sampling
