the main technical characteristics of gas chromatograph:
1, the instrument uses large-screen LCD liquid crystal display technology, display intuitive, easy to operate, more suitable for China's national conditions.
2, self-diagnostic function, with "0 ºC" protection. When any of the temperature display is always "0 ºC", will automatically stop heating to prevent the chamber is always heated lead to damage to the heating element and a Chinese prompted the cause of the malfunction and alarm.
3, touch-sensitive keyboard to facilitate the operation of the user data set.
4, data power protection, the instrument set the operating data in the power after the long-term preservation.
5, microcomputer control FID detector automatic ignition, with a stopwatch timing function.
6, with over-temperature protection device. When the temperature exceeds the set limit, the instrument stops heating and reports a fault on the display.
7, through the large-screen LCD Chinese display intuitive display of the instrument parameters, through the user-friendly software interface, greatly facilitate the user to set the various road temperature, Cheng Sheng, detector, bridge flow and other parameters; intuitive operation switch bridge flow , Turn off the temperature control, open and close the process of lifting and various events and other functions.
8, the instrument computer connected to the Internet, through a remote computer and instrument connection, remote data acquisition and management. Improve the freedom of the device, and promote the effective application of the laboratory.
9, the main control circuit uses a function of advanced microprocessors, large-capacity memory used, so that the preservation of more reliable data. At the same time set the measurement, control, power supply in a circuit board of the integrated design of the instrument to improve the anti-interference and reliability.
10, the use of microprocessor temperature control circuit, the heating area of the object to be controlled temperature accuracy of 0.1 degrees.
11, intelligent double rear door technology to ensure the instrument oven temperature has a good temperature control accuracy, and can quickly cool down.
12, eight-order temperature program to adapt to the analysis of a wide boiling point of the complex samples.
13, the overall structure of the unit design, installation, easy maintenance.
14, large volume oven, can be installed at the same time four columns.
15, reasonable and flexible instrument design, you can install three detectors, and an independent circuit system, the signal output.
16, flexible packed column and capillary column system, can be accessed by different caliber capillary column.
17, with gas protection and Chinese tips function, to maximize the protection of TCD tungsten wire and the column from damage.
gas chromatography main technical indicators:

Detector: room temperature 5 ºC -420 ºC Accuracy ± 0.1 ºC (200 ºC when measured). Up to six-way temperature control: for the installation of multi-converter temperature control needs.
2, column thermostat parameters: temperature control accuracy: room temperature 5 ºC -420 ºC accuracy ± 0.1 ºC. Column thermostat volume: 280mm × 280mm × 250mm. Program heating order: eighth order. Program temperature rise rate: 1 ºC -50 ºC. Hold time of each order: 0-300min (1min increments). Automatic rear door design to ensure rapid cooling. High-power, low-noise rotating fan to ensure uniformity of temperature.
3, the stability of the dual-gas system: carrier gas flow after the first steady flow of the dual stability of the design. Accurate scale pneumatic control valve parts, with high reproducibility and high stability.
4, a variety of sampling options: packed column stigma injection. Packed column gasification sampling. Capillary Split / Splitless Injection: Backpressure valve control technology, linear shunt. Six - way valve gas sampling.
Third, the benzene series gas chromatograph High sensitivity detector parameters to ensure the accuracy of the data Detector sensitivity / sensitivity Noise drift linearity FIDMf ≤ 5 × 10-12g / s (benzene) ≤ 0.02mV ≤ 0.15mV / h ≥ (Benzene) ≤ 0.02mV ≤ 0.15mV / h ≥ 105 Imports of rhenium tungsten wire, constant current power supply ECDM ≤ 2 × 10-14g / ml (r-666) Information Name: Supply of imported rhenium tungsten wire, constant current power supply ECDM ≤ 2 × 10-14g / ml ) ≤ 0.02mV ≤ 0.15mV / h≥104 High temperature resistant Ni63 radioactive source FPDMp≤2 × 10-11g / sec (1605) Ms≤5 × 10-11g / sec (thiophene) ≤ 0.02mV ≤ 0.15mV / h≥103 Single flame design, for residue analysis NPDMf ≤ 5 × 10-12g / s (azobenzene) Mf ≤ 5 × 10-12g / s (malathion) ≤ 0.02mV ≤ 0.15mV / h ≥ 103 imported bead , For residual analysis Note: Dimensions: 660 * 460 * 465mm Weight: 60 kg Input power: AC 220V ± 10% 50HZ 2KW10% 50HZ 2KW
