Features:

microcomputer control circuit system

1, the instrument adopts the whole machine self-micro control system, adjustable LCD screen, rich and intuitive display, touch keyboard, Chinese display, digital zero, automatic ignition, convenient to set the operation data

2, the use of new dual CPU design, the original Japanese highly integrated electronic circuit technology, excellent reliability and anti-interference ability, temperature control accuracy of 0.1℃, higher display accuracy of 0.01℃, and can also display the percentage of power consumption of each heating part.

3, the main control circuit adopts the microprocessor, the use of large capacity memory, so that the data storage is more reliable.

4, with power failure protection function, automatic memory setting parameters; It has the function of anti-power mutation interference and stopwatch timing.

5, with overtemperature protection device. Temperature exceeds the set limit, the instrument will stop heating, automatic alarm and prompt fault on the display.

6, the product has the function of gasless protection and prompt, to protect the TCD tungsten wire and chromatographic column from damage.

7, with a wide range of fault self-diagnosis function, fault self-diagnosis information, at any time to display the fault cause and treatment method.

8, instrument computer connected to the Internet, through the remote computer and instrument connection, remote data acquisition and management. The freedom of the device is improved and the effective application of the laboratory is promoted.

9, column room with frequency conversion intelligent after the door automatic cooling system, cooling speed is very fast, (from 280℃ to 50℃ only takes 5 minutes) to achieve the true meaning of near room temperature operation.

10. Six-channel temperature control: suitable for multi-channel temperature control requirements such as adding reformer. Column chamber, vaporization chamber, hydrogen flame detection chamber, thermal conductivity detection chamber, auxiliary 1, auxiliary 2 all adopt modular design, more convenient installation and replacement.

11, with FID, TCD, ECD, FPD and other detector options.

stable gas path system:

1. Carrier gas flow adopts the dual stability design of stabilizing pressure first and stabilizing flow later;

2, accurate air path control valve parts, with high reproducibility and high stability.

3. At the same time, it is equipped with a packed column vaporizing chamber and an independent capillary special system. The design of the vaporizing chamber is based on the miniaturized design of the same type of products from abroad.

a variety of sampling methods are optional;

(1) Sample injection of packed column capitals

(2) Filling column gasification injection (

3) capillary shunt/non-shunt injection; Back pressure valve control technology, linear shunt;

(4) six-way valve gas sampling;

(5) Automatic headspace sampling;
