Product Usage

It can be widely used in environmental protection, food safety, electronics industry, flavor and fragrance industry, textile industry, petrochemical industry, pharmaceutical industry, judicial appraisal and other fields. Analysis of organic pollutants in the environment (analysis of pollution in air, water quality, and soil); analysis of pesticide residues and additives in food; detection of harmful substances in the electronic and electrical industry, analysis of aroma components in flavors and fragrances.


Features:

1. The instrument adopts Chinese 5.7-inch large-screen LCD liquid crystal Chinese character display technology, which is intuitive to display and easy to operate.

2. Self-diagnosis function, with "0°C" protection function. When the temperature display of any channel is always "0°C", the heating will be automatically stopped to prevent the heating body from being damaged due to the constant heating of the chamber. There are also Chinese prompts indicating the cause of the failure and an alarm prompt.

3. The touch keyboard is convenient for users to set various operation data.

4. Data power failure protection function, the operating data set by the instrument can be saved for a long time after power failure. 5. The microcomputer controls the automatic ignition of the FID detector, and has the function of a stopwatch.

6. With over-temperature protection device. If the temperature exceeds the set limit, the instrument will stop heating and report a fault on the display.

7. The instrument parameters are intuitively displayed through the large-screen LCD Chinese display. Through the user-friendly software operation interface, it is very convenient for users to set parameters including temperature, range rise, detector, bridge current and other parameters; intuitively operate the switch bridge current , turn on and off the temperature control, turn on and off the step-up and various time events and other functions.

8. The computer of the instrument is connected to the Internet, and can be connected to the instrument through a remote computer to realize remote data collection and management. The degree of freedom of the device is improved, and the effective application of the laboratory is promoted.

9. The main control circuit adopts a microprocessor and a large-capacity memory, which makes data storage more reliable. At the same time, the integrated module design integrating measurement, control and power supply on one circuit board improves the anti-interference and reliability of the instrument.

10. Using the temperature control circuit of the microprocessor, the temperature accuracy of the controlled object in each heating zone reaches 0.1 degrees.

11. The intelligent double back door technology ensures good temperature control accuracy of the instrument oven temperature and can achieve rapid cooling.

12. Eight-stage temperature programming, suitable for the analysis of complex samples with wide boiling points.

13. The large-volume column box can install four chromatographic columns at the same time; the unitary overall structure design is convenient for installation and maintenance.

14. The design of the instrument is reasonable and flexible, and three detectors can be installed at the same time, and it has an independent circuit system and signal output terminal. Equipped with FID, TCD, ECD, FPD, NPD and other detector options.

15. Flexible packed column and capillary split/splitless sampling system, which can be connected to capillary columns of different diameters.

16. A variety of sampling methods are available, such as manual six-way valve sampling, electric ten-way valve sampling, headspace sampling, automatic sampler sampling, thermal desorption sampling, pyrolysis sampling, and A methane reformer system can be added.
