Grounding requirement resistance: ＜ 0.1Ω
2. Gas source requirements:
Nitrogen: 99.995%
Hydrogen: 99.995%
Air: dry and oil-free
3. Basic operating requirements for hydrogen flame ionization detector (FID)
Carrier gas: flow rate 50ml/min (30-80 ml/min)
Hydrogen gas: flow rate 30ml/min (25-40 ml/min)
Air flow rate: 350 ml/min (250-500 ml/min)
4. Basic operating requirements for thermal conductivity detector (TCD)
Before starting up, the carrier gas should be supplied for 30 minutes with a flow rate of 50ml/min, and then the machine should be turned on for heating
Flow correction, two outlet flow deviation ≤ 1%
According to the analysis requirements, set the size of the bridge flow value
When using nitrogen as the carrier gas, the bridge flow should be appropriately reduced compared to hydrogen as the carrier gas
5. Electronic Capture Detector (ECD) gas source requirement: Nitrogen: 99.999%
And install a deoxygenation tube. Before starting up, the carrier gas should be supplied for 2 hours with a flow rate of 80ml/min, and then the machine should be turned on for heating
6. Special reminder: First supply the carrier gas, then turn on the machine to increase the temperature!

Performance characteristics of SP6890 gas chromatograph

1The instrument adopts a fully microcomputer automatic control system,Adjustable LCD display screen, displaying rich and intuitive content; Chinese keyboard style operation, setting parameters and operation are very convenient.
2 Adopting brand new doubleCPUDesign, original Japanese high integration electronic circuit technology,Excellent reliability and anti-interference ability,The precision of temperature control has reached0.1℃, with higher display accuracy0.01℃And it can simultaneously display the power consumption percentage of each heating part.
3Design of Three Gas Channels and Large Volume Column Chambers,Can install three chromatography columns simultaneously and simultaneouslyFID、TCDTwo types of detectors, And it can be easily expandedECD、FPD、NPDThree types of detectors, as well as external control equipment such as gas injectors and converters.
4This machine can be easily converted from a single deviceFIDAmplifier expanded to dualFIDThe amplifier truly achieves multi-purpose use for one machine.
5Equipped with two packed column vaporization chambers and an independent capillary system, the design of the vaporization chamber draws on the miniaturization design of similar foreign products, with fast heating speed and no injection dead corners,Has excellent capillary diversion capability/The non split sampler and tail blowing system can easily install small-diameter capillary columns, large-diameter capillary columns, and various packed columns.
6Equipped with a five order linear program heating function,Satisfied with multi-component sample analysis.
7The column chamber is equipped with a variable frequency intelligent rear door automatic cooling system, The cooling rate is very fast,(follow280℃drop to50℃It only needs5minute Realized true near room temperature operation.
8Equipped with six independent temperature control systems.Suitable for installing multiple temperature control requirements such as conversion furnaces;Column chamber, gasification chamber, hydrogen flame detection chamber, thermal conductivity detection chamber, auxiliary1Assist2All adopt modular design,Installation and replacement are more convenient.
9It has power failure protection function and can automatically memorize set parameters. It has anti power mutation interference function and stopwatch timing function.
10It has an over temperature protection function, which automatically shuts off and alarms when the temperature exceeds the set upper limit. If the temperature of any circuit exceeds the set temperature, heating will automatically stop; And there are prompts for the cause of the malfunction and alarm notifications.

11Having0℃”Protection function. When any temperature display is consistently0℃”When, All heating will automatically stop to prevent the heating element from being damaged due to constant heating in the room.And there are prompts for the cause of the fault and alarm prompts
12Among similar products, the gas cut-off protection and prompt function can provide maximum protection to the greatest extent possibleTCDThe tungsten wire and chromatographic column are not damaged.
13It has a wide range of fault self diagnosis functions,36Plant self diagnostic information, display the cause of the fault and its handling methods at any time.
14Stable pneumatic system:
(1)The carrier gas flow rate adopts a dual stability design of first stabilizing the pressure and then stabilizing the current;
(2)Accurate pneumatic control valve components with high reproducibility and stability.
15Multiple injection methods are available:
(1)Fill the column head for injection;
(2)Filling column gasification injection;
(3)Capillary diversion/Non diversion injection: back pressure valve control technology, linear diversion;
(4)Six way valve gas injection;

(5)Automatic headspace injection;
