Application Industry
1. Analysis of dissolved gas in transformer oil;
2. Analysis of ethylene oxide in medical devices.
3. Analysis of coke oven gas;
4. Pesticide residue analysis;
Alcohol analysis in blood; 5.
6. Analysis of natural gas and liquefied gas;
7. Indoor environment TVOC analysis;
8. Analysis of liquor components;
9. High purity gas analysis;

The Performance Characteristics
1. The third order process is heating up, which can satisfy the analysis demand of the multi-component of the sample.
1) main control circuit adopts new integrated digital electronic circuit, temperature control precision of 0.01 ℃, the performance is more stable;
2) temperature programmed: 13 order, heating rate 0 to 50 ℃ / min. The incremental 0.1 ℃ / min;
2. The design of the column box is further improved to facilitate the rapid cooling of the instrument.
1) the volume is large, and it is the intelligent rear door opening system, which reduces the stable balance time of the system after the program rise/cooling system;
2) system of heating furnace temperature range is + 7 ℃ ~ 400 ℃;
3) the user can recalibrate the furnace temperature and set the maximum temperature and temperature balance time of the heating furnace.
3. Unique and selective enhancement of the sample system.
1) unique sample entrance design solves the sample discrimination;
2) two sampling systems can be installed at the same time: filled column, capillary diverter/non-shunt injection system (with diaphragm cleaning function);
3) optional automatic/manual gas six - pass injection valve sampler, headspace injector, heat analyser, pyrolysis furnace, methanol converter.
4) double column compensation work can not only solve the program drift caused by heating, but also reduce the influence of background noise, and can get lower minimum detection limit.
4. The instrument operation interface is simple and easy to learn, with complete functions and a more humanized design.
1) the instrument adopts large-screen LCD screen, which is intuitive and easy to operate;
2) it has the function of starting up self-diagnosis;
3) stopwatch function (convenient flow measurement) and operation timer function;
4) power failure storage protection function;
5) keyboard locking function.
5. Good stability, high sensitivity and multiple detectors.
1) which can be installed at the same time two kinds of the same or different detector: hydrogen flame ionization detector (FID), the thermal conductivity detector (TCD), electron capture detector (ECD), nitrogen and phosphorus detector (NPD), flame photometric detector (FPD), etc.
2) hydrogen flame ionization detector is easy to be disassembled and installed for easy cleaning or replacement of nozzle;
3) high detection sensitivity of high resistance single column thermal conductivity detector, stable baseline stability (stable in 15 minutes);
4) input signals can be used for logarithmic amplification, reduce interference and improve sensitivity.
