factory low price Face Mask Respirator Flame Retardant Tester - GC-1690 Gas Chromatograph – Yueyang

GC1690 series high performance gas chromatograph is according to the use of optional combination of hydrogen flame ionization (FID), thermal conductivity (TCD) two kinds of detector, can be boiling point below 399℃ organic matter, inorganic matter and gas for constant, trace and even trace analysis.

Widely used in petroleum, chemical, fertilizer, pharmaceutical, electric power, food, fermentation, environmental protection and metallurgy and other fields.

GC1690 series high performance gas chromatograph adopts international advanced technology, integrating the advantages of domestic gas chromatograph and developed into the latest generation of gas chromatograph.

According to the use of flexible matching hydrogen flame ionization (FID), thermal conductivity (TCD), flame photometry (FPD), nitrogen and phosphorus (NPD) and other detectors, can be boiling point below 399℃ organic matter, inorganic matter and gas for constant, trace and even trace analysis.

Widely used in petroleum, chemical, fertilizer, pharmaceutical, electric power, food, fermentation, environmental protection and metallurgy and other fields.

GC16 series with excellent cost performance and perfect after-sales service has become the first choice of many domestic gas users.

The new model uses back pressure valve split/no split mode

Column temperature box:

The use of recognized high performance large column temperature box considering the heat radiation generated by heating gasification chamber or detector, column temperature box is designed to be vertical structure, the highest use temperature can reach 420℃, temperature control range +7℃~420℃, the fifth order program heating, automatic rear door, can be set 420℃ high use temperature, fixed 450℃ independent protection circuit, It has a double protective structure.

1. Fill the column with an upward sample

2. Shunt/non-shunt injection

3. Large diameter capillary WBC injection

4. Fill column by vaporization

5. Six-way valve air intake style

Column temperature box

1.Temperature control range: RT +7 ° C ~420 ° C

2.The temperature control accuracy is better than ±0.1℃

3.The internal volume is: 240×160×360mm

4.Program order: 5

5.Temperature rise rate: 0.1~39.9℃/min arbitrary setting

6.Heating time: 0~665min(increment 1min)

*1. Overtemperature protection:

when the actual temperature of each hot area exceeds the set maximum value, the overtemperature protection device will work, automatically cut off the power supply of each heating area of the instrument, and alarm to avoid accidents.

*2. Overcurrent protection:

When TCD detector work, such as excessive current Settings or TCD resistance suddenly increases, the over-current protection device, automatic cut off the current TCD bridge, at the same time, alarm and display OVER TCD in order to protect the tungsten wire is not burned (if the user due to error, in the case of not TongZai gas start TCD, the device can automatically cut off the power supply to protect the tungsten wire).

Amplifying circuits can also be added to increase sensitivity.

*3. Crash protection:

when the instrument is working, when there is a heat sensitive element short circuit, open circuit, heating wire to the ground, microcomputer operating system crash, the instrument can automatically cut off the power and alarm, to avoid continuing to work and accident.

The above three protection functions can make you more secure analysis work.

GC1690 gas chromatograph can carry out six temperature control, AUX1 control external heating device, column temperature AUX1 with five order program heating.

The gas path controller adopts the external type, the capillary gas path box, the gas auxiliary gas path box is placed independently, the airflow ratio adjustment is intuitive and easy to understand, the control is flexible, and once there is a gas path problem can immediately switch, has no influence on the main engine operation, easy to maintain.

Each blade in the main engine is moulded once, with good symmetry to avoid unbalance and noise during operation.

The capillary injector is independent and can be equipped with double magnifying plate of double capillary injector to install two capillary columns at the same time.

Two packed columns can also be installed at the same time;

A packed column and a capillary column can also be installed simultaneously;

TCD, FPD, NPD, ECD detectors can also be flexibly added on this basis to meet different analysis requirements;

A maximum of three samplers and three detectors can be installed in one instrument.

With vertical column box, beautiful appearance, and small occupation area, suitable for the use of narrow laboratory space.

“*” indicates that the technology is the first of its kind in China.

Chemical industry, hospital, petroleum, distillery, environmental testing, food hygiene, soil, pesticide residue, papermaking, electricity, mining, commodity inspection, etc.
