Key Performance Features:

1. The instrument features a full microcomputer automatic control system, with an adjustable LCD display that offers 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-integrated Japanese electronic circuit technology, offering excellent reliability and anti-interference capabilities. The temperature control precision reaches 0.1°C, with the display accuracy up to 0.01°C, and it can simultaneously show the power consumption percentage of each heating section.

3. The design features a triple gas path and a large-volume column chamber, allowing 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, and the addition of gas injection systems and reformers, among other external control equipment.

4. The machine can be easily expanded from a single FID amplifier to a dual FID amplifier, truly realizing multi-functional use with one unit.

5. Equipped with two packed column vaporization chambers and an independent capillary tube system. The vaporization chamber design draws inspiration from the miniaturized design of similar foreign products, offering fast heating, no sampling dead spots, and excellent capillary分流/不分流 injectors and tail gas systems. It allows for easy installation of small-bore capillary columns, large-bore capillary columns, and various packed columns.

6. Features a five-stage linear temperature ramping function, suitable for analysis of multi-component samples.

7. The column chamber features a variable frequency intelligent automatic cooling system, which cools down rapidly (from 280℃ to 50℃ in just 5 minutes), achieving near-room temperature operation in a true sense.

8. Equipped with a six-way independent temperature control system, suitable for applications requiring multiple temperature controls, 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 feature modular design for easy installation and replacement.

9. Features power failure protection and auto-memorization of set parameters. Equipped with anti-power surge interference and stopwatch timing functions.

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; with an indication of the fault cause and alarm prompt.

11. Features "0℃" protection. If any temperature display remains at "0℃" at all times, the heating will automatically shut off to prevent damage to the heating element from continuous heating. It also provides a fault cause prompt and an alarm alert.

12. Our product features an air-cut protection and alert function, which maximizes protection for TCD tungsten filaments and chromatography columns from damage.

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

14. Stable airway system:

(1) The gas flow utilizes a dual stability design with pressure stabilization followed by flow stabilization.

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

15. Multiple sample submission methods available:

(1) Filling column head sample insertion

(2) Filled column gas chromatography injection

(3) Capillary Split/Splitless Injection: Backpressure valve control technology, linear splitting.

(4) Six-way valve gas sampling

(5) Automated headspace sampling

Detector Technical Specifications:

Attachment 1: (This unit is configured with a FID detector, featuring available interface for additional options, allowing the addition of any two out of detectors 2, 3, 4, or 5)

1. The TCD detector (Thermal Conductivity Detector) is one of the most widely used detectors, suitable for inorganic gases and organic compounds, particularly well-suited for constant analysis or analysis of components at concentrations above ten parts per million.

2. FID Detector (Hydrogen Flame Ionization Detector) with high sensitivity, suitable for trace analysis of organic substances.

3. The ECD detector (Electron Capture Detector) is a low-energy radioactive detector widely used in atmospheric and water quality pollution detection. It is suitable for analyzing organic complexes of halides, polyhalides, polycyclic aromatic hydrocarbons, and metal ions.

4. FPD Detector (Flame Photometric Detector), suitable for analyzing phosphorus-containing compounds and monitoring trace levels of phosphorus-containing organic pollutants in environmental analysis.

5. The NPD detector (Nitrogen-Phosphorus Detector) is a quality tester suitable for the high-sensitivity and high-selectivity detection of nitrogen and phosphorus compounds; it can detect nitrogen-containing compounds like azobenzene at a level of 5×10(-13) g/s and phosphorus compounds such as Marathon at 2.5×10(-13) g/s. It has a high response to nitrogen and phosphorus compounds and a low response to other compounds, typically 10,000 to 100,000 times lower.
