Portable chromatograph

GC-7890Type gas chromatograph

GC-7890The type of gas chromatograph is Jinan Qiancheng Analytical Instrument Co., Ltd. has developed a new generation of chromatography products using foreign technology. Large screen color displayLCDThe graph display intelligent digital counter control workstation is more convenient to operate. High sensitivity, high stability detector, good reproducibility, and outstanding detection performance.

Portable chromatographPerformance characteristics:

※ Information rich LCD display:This machine adopts a 5.7-inch LCD display, with a large screen displaying Chinese (English) interchangeably, providing clear and intuitive images. Six temperature control values (set and actual values for column box, sampler, detector, auxiliary furnace, etc.) can be displayed simultaneously on the same interface, with reserved fault alarm location area, time display area, event area, etc

※Easy to understand Chinese operation keyboard: It can intuitively set parameters such as temperature, time, events, range rise, stopwatch, extreme temperature protection value, detector range, polarity, current, etc. of the instrument. With one click operation, you can learn instrument operation in a short time (foolproof operation)

※ofFIDFeaturing low detection limits, convenient disassembly, cleaning, and precise fixation of the nozzle and ion collection electrode, the emission set installation structure ensures the high performance of each instrument;

※Analyze application requirements based on different customer needs,Flexible installation options availableFPD、NPD、ECDDetector;

※high sensitivityTCDUsing high resistance rhenium tungsten wire and providing2Electronic amplification circuit with sensitivity up to6000mV·ml/mg,The air insulation structure makesTCDHas higher stability;

※The main control circuit adopts a functional microprocessor and a large capacityFLASHFlash memory andEEPROMMemory, data storage is more reliable. The design of integrating measurement, control, and power into one circuit board has improved the anti-interference and reliability of the instrument;

※ GC-7890Equipped with a dual over temperature protection device, the instrument will stop heating and send an error message regardless of which temperature exceeds the set value, ensuring the use of the instrument;

※The intelligent back door technology ensures that the instrument can have good temperature control accuracy even when the column temperature is close to room temperature. At the same time, the prevention and control measures adopted for the chromatographic baseline burrs caused by rapid cooling on the chromatographic column loss include chromatographic graphics.

※ Temperature program8rank9The platform's capabilities can be expanded according to customer requirements16rank,Adapt to the analysis of complex samples with wide boiling range and low content;

※ GC-7890Provide multiple options for injectors and detectors. Fill the column for injection, gas injection, and instantaneous vaporization injection; Capillary injection without diversion, capillary diversion/No diversion injection, direct injection into large-diameter columns; Clean the injector with a diaphragm, etc.
