Gas chromatograph

Main performance characteristic:1, the instrument used the entire microcomputer automatic control system, the zoom type liquid crystal display monitor, the demonstration full of meat have been direct-viewing; Chinese keyboard type operation, the setup parameter and the operation are convenient.2, uses the electronic circuit technology which the brand-new double CPU design, the original installation Japanese Gaoji becomes, the fine reliability and antijamming ability, control the warm precision to achieve 0.1℃, demonstrated that the precision reaches as high as 0.01℃.

3, the keyboard establish each kind of control and the detector parameter, within the aircraft have the breakdown from functions and so on diagnosis, file memory, power failure protection, and may remember automatically the setup parameter.

4, may act according to the operation requirements choice many kinds of detector combinations: FID, TCD, FPD, ECD, NPD and so on.5, the instrument simultaneously install the packing column and the capillary vessel column two kind of air course systems, can satisfy the present chromatograph analysis to each kind of chromatographic column selection and the analysis operation requirements.6, the fine column box performance, after the column room has the frequency conversion intellectualization, opened the door the automatic temperature decrease system, the temperature decrease speed is quick, realizes near room temperature in the true sense to hold Making.

Has the fifth-order linear program elevation of temperature function, satisfies in the multi-component sample analysis.7, the vaporizer design has profited from the overseas same type product miniaturized design, the elevation of temperature speed quick, the non-specimen handling dead angle, has the fine capillary vessel divergence/not to diverge the sample injector and the tail blows the system, but installs the small caliber capillarity column, the heavy-caliber capillarity column and each kind of packing column conveniently. controls the target warm: 1) column Box: Room temperature +5 ℃--400 ℃ Controls the warm precision: Earth 0.1℃ Demonstrated that the precision reaches as high as: 0.01℃ 2) temperature program exponent number: Fifth-order linear Cheng Sheng 3) controls the warm way: 5 groups (may expand are 6 groups) 4) the temperature program speed: 0.

1℃~40℃ /min (0.1℃ increase) 5) various steps constant temperature maintains the time: 0~ 9999.9 min (0.1min increase) detector technical specification: detector hydrogen flame ionization detector (FID) heat conductivity detector (TCD) sensitivity Mt≤1×10-11g/s (benzene) S≥ (benzene) noise ≤0.02mv ≤0.02mv drifting ≤0.1mv/h ≤0.15mv/h
