Product Introduction

GC1690The series of high-performance gas chromatographs isDRICKThe laboratory analytical instruments introduced by the company to the market can be optionally combined with hydrogen flame ionization according to usage needs（FID）Thermal conductivity（TCD)Two types of detectors that can detect boiling points399.CPerform constant, trace, and even trace analysis on the following organic, inorganic, and gas substances. Widely used in fields such as petroleum, chemical, fertilizer, pharmaceuticals, electricity, food, fermentation, environmental protection, and metallurgy.
GC1690The series of high-performance gas chromatographs isDRICKA first generation gas chromatograph developed by integrating the advantages of domestic gas chromatographs using technology. Flexible selection of hydrogen flame ionization according to usage needs（FID）Thermal conductivity（TCD)Flame luminosity（FPD）Nitrogen and phosphorus（NPD）Waiting for the detector, it can detect the boiling point399Perform constant, trace, and even trace analysis on organic, inorganic, and gas substances below ℃.

GC1690The series has also become a product for many gas-phase users in China due to its excellent cost-effectiveness and comprehensive after-sales service.

Product Features

The new model adopts back pressure valve diversion/Non diversion mode

column oven

Considering the thermal radiation generated by the heating of the gasification chamber or detector, the high-performance column temperature box obtained is designed as an upright structure, and the operating temperature can reach420℃,Temperature control range+7℃~420℃，5Step program temperature rise, automatic rear door opening, can be set420Temperature for use at heights within ℃, fixed450℃ independent protection circuit with dual protection structure.

*1Over temperature protection: When the actual temperature of each hot zone exceeds the set value, the over temperature protection device works, automatically cutting off the power supply of each heating zone of the instrument, and sounding an alarm to avoid accidents.

*2Overcurrent protection: WhenTCDWhen the detector is working, if the current is set too high orTCDWhen the resistance suddenly increases, the overcurrent protection device works and automatically cuts offTCDBridge current, alarm and display simultaneouslyOVER TCDTo protect the tungsten wire from burning out (if the user starts it without gas supply due to operational errors)TCDThe device can also automatically cut off the power to protect the tungsten wire; Amplification circuits can also be added to increase sensitivity.

*3Crash protection: When the instrument is in operation, if there is a short circuit, open circuit, heating wire to ground, or microcomputer operating system crash in the thermistor of each heating zone, the instrument can automatically cut off the power and give an alarm to avoid accidents caused by continuing to work; The above three protection functions can make your analysis work safer and more reassuring.

Six major temperature controls

GC1690The gas chromatograph is capable of six temperature control channels, among whichAUX1Control external heating device, column temperature andAUX1Equipped with a five stage program for heating up.

Pneumatic control

The gas path controller adopts an external type, with capillary gas path box and gas combustion assisting gas path box placed independently. The airflow ratio adjustment is intuitive and easy to understand, and the control is flexible. Moreover, once a certain gas path problem occurs, it can be immediately switched, which has no impact on the operation of the host and is easy to maintain.

low noise

Each fan blade inside the host is molded in one go using molds, with good symmetry to avoid imbalance and noise during operation.

Flexible configuration

The capillary injector is independent and can be configured with dual capillary injectors and dual amplification plates according to user requirements, allowing for the simultaneous installation of two capillary columns; Two filling columns can also be installed simultaneously; It is also possible to install both a packed column and a capillary column simultaneously; It can also be flexibly increased on this basisTCDTheFPDTheNPDTheECDDetector to meet different analysis requirements; One instrument can be equipped with up to three types of injectors and three types of detectors.

Beautiful appearance

Using a vertical column box, it has a beautiful and elegant appearance, and occupies a small area, suitable for use in small laboratory spaces.
