DK3001 Headspace Chromatogram Alcohol Analyzer  |
| Drunk driving seriously violates the traffic rules of China , and whether the driver is drunk driving is one of the important basis for identifying the responsibilities of the accidents when handling the traffic accidents. Headspace chromatogram method is adopted worldwide to accurately detect the alcohol contents in driver's blood. However, since the price of the imported equipment is too expensive, it is impossible for this kind of equipment being applied in low-level traffic police stations. With reference to the similar products produced in other countries and based on the real situation of China , by take years research and development, the company has developed the DK3001 Headspace Chromatogram Alcohol Analyzer. With its high sensitivity, fast analyzing speed, and stable operation, it can accurately detect the alcohol content in human's blood just within two minutes. This machine has been widely applying in the public security system. Its effect is obvious and highly appraised by the users. Our company are willing to become your reliable friend by providing your high quality products and services. |

| Logging Gas Chromatography |
| Logging gas chromatography is a new type special chromatography developed and designed on the basis of introducing and assimilating GC3400 manufacturing technology from American Varian Company, and it keeps all the functions of GC3400 gas chromatography. The machine adopts packed column, quartz capillary multidimensional column, valve switch systems, and a single injection can conduct fast analysis on C1-C4 and other ingredients. Its analysis speed is fast, it can finish the analysis on C1-C4 within two minutes.
The machine adopts the latest automatic switch valve design. The valve is easy to operate, and without extra-column volume effect and only one valve operation is required for each analytical cycle so that it reduces the times of the operation. Thus, the valve’s life-span could reach over 100000 times. There are four external event program operations, and all valves and the detector signals are automatically switched by the pre-set programs.
It can work with all kinds of common chromatogram data workstations and conduct fast computation on the chromatogram. The original data could be stored permanently and it could be accessed and reprocessed at any time. |
| Technical parameters：
- Column box tem temperature: above room temperature （20-350℃）
- Temperature programming: 1-4 level linear temperature programming can be set, the rate is 0.1-50℃/min.
- Detector temperature: above room temperature （20-350℃）
- Injector temperature: above room temperature （20-350℃）
- Valve box temperature: 50℃
- TCD sensitivity: ≥5000mvml/mg(sample butane)
- FID detecting limit：≤8×10-12g/s(N-C16)
- Ingredients to be analysed: C1，C2，C3，C4，H2，CO2，∑C

| Liquid Oxygen Hydrocarbon Compound Gas Chromatography |
| In the production procedure of steel mills and petroleum & chemical plants, the gas separation equipment is an important part of the whole procedure. The working principle of the gas separation equipment is to gradually condense the concentration into liquid oxygen from the hydrocarbon compound in the air, and when the concentration of the hydrocarbon compound reach its limit, it can lead to cold explosion and cause series accident. In order to ensure the safe operation of gas separation equipment, it is necessary to check the ingredients and contents of the hydrocarbon compound in the liquid oxygen, and to identify the equipment fault in its early stage so as to take measures to deal with the problem, by doing so, it can avoid occurrence of the series accident and reduce the unnecessary loss.
To satisfy the needs of the domestic users, our company has developed Special Liquid Oxygen Hydrocarbon Compound Gas Chromatogram System. The system is equipped with high sensitivity flamboyance detection chromatography by introducing American technologies, imported chromatogram column and six routes automatic injection valves, professional chromatogram analytical workstation, and calibration standard gas.
