Factory Direct: DRK-GC-1690 Gas Chromatograph - Precision And Performance Guaranteed

Introduction: According to the regulations in GB15980-2009, the residual amount of ethylene oxide in disposable syringes, surgical gauze and other medical supplies should be no more than 10ug/g, which is regarded as qualified. The DRK-GC-1690 gas chromatograph is specifically designed for epoxy in medical devices Detection of residual amounts of ethane and epichlorohydrin. It also meets the ISO 13683 standard. Product Brief DRK-GC-1690 series high-performance gas chromatograph is the latest generation of gas chromatograph developed by Derek Instruments Co., Ltd. by adopting international advanced technology and integrating the advantages of domestic gas chromatograph. It can be flexibly equipped with detectors such as hydrogen flame ionization (FID), thermal conductivity (TCD), flame photometric (FPD), nitrogen and phosphorus (NPD) according to the needs of the application, and can be constant for organic substances, inorganic substances and gases with a boiling point below 399℃ , Trace and even trace analysis. It is widely used in many fields such as petroleum, chemical industry, fertilizer, pharmacy, electric power, food, fermentation, environmental protection and metallurgy. The GC16 series has also become the first choice for many domestic gas phase users with excellent cost performance and perfect after-sales service. Main Feature The new model adopts backpressure valve split/splitless mode Column thermostat Use of the well-recognized high-performance large column thermostat Considering the heat radiation generated by the heating of the gasification chamber or the detector, the column thermostat is designed as an upright structure, the maximum use temperature can reach 420℃, and the temperature control range is +7℃~420℃, 5 steps program temperature increase, automatic door opening, can be set within 420 ℃ high use temperature, fixed 450 ℃ independent protection circuit, with double protection structure. Sampler 1. Inject on packed column 2. Split/splitless injection 3. Large-bore capillary WBC injection 4. Packed column vaporization sampling 5. Six-port valve air inlet style Main Specifications

*1, over-temperature protection: when the actual temperature of each hot zone exceeds the set maximum value, the over-temperature protection device works, automatically cuts off the power supply of each heating zone of the instrument, and alarms to avoid accidents. *2. Over-current protection: when the TCD detector is working, such as when the current setting is too large or the TCD resistance value suddenly increases, the over-current protection device works, automatically cuts off the TCD bridge current, and simultaneously alarms and displays OVER TCD to protect the tungsten wire from Burned (If the user starts the TCD without carrier gas due to operating errors, the device can also automatically cut off the power to protect the tungsten wire). An amplifier circuit can also be added to increase sensitivity. *3. Crash protection: When the instrument is working, when the thermal elements of each heating area are short-circuited, broken, the heating wire is to the ground, and the computer operating system crashes, etc., the instrument can automatically cut off the power and alarm to avoid the occurrence of continuous work. accident. The above three-point protection function can make your analysis work more safe and secure. Six temperature controls The DRK-GC-1690 gas chromatograph can perform six-channel temperature control, in which AUX1 controls the external heating device, and the column temperature and AUX1 have a five-step program temperature increase. Pneumatic control The gas path controller is external, the capillary gas path box and the gas-assisted gas path box are placed separately. The air flow ratio adjustment is intuitive and easy to understand, and the control is flexible. In addition, once a certain gas path problem occurs, it can be switched immediately, without affecting the operation of the host, maintenance Convenience. Low noise The fan blades in the main machine are formed by a mold at one time, and the symmetry is good, so as to avoid unbalance and noise during operation. Flexible configuration The capillary sampler is independent and can be equipped with dual capillary sampler dual amplification plates according to user requirements, so that two capillary columns can be installed at the same time; two packed columns can also be installed at the same time; one packed column and one capillary can also be installed at the same time Column; TCD, FPD, NPD, ECD detectors can also be flexibly added on this basis to meet different analysis requirements; one instrument can be installed with up to three injectors and three detectors. Beautiful appearance The vertical column box is used, which has a beautiful and elegant appearance and a small occupied area. The "*" indicates that this technology is the first in China.
