Dimethyl ether gas chromatography analyzer

GC-7890Type gas chromatograph

The GC-7890 gas chromatography analyzer for dimethyl ether is a generation chromatography product developed by Jinan Qiancheng Analytical Instrument Co., Ltd. using foreign technology. Large screen color LCD map display digital control workstation, easy to operate. High sensitivity, high stability detector, good reproducibility and detection performance.

Dimethyl ether gas chromatography analyzerPerformance characteristics:

※ Information rich LCD display: This machine adopts a 5.7-inch LCD display, with a large screen displaying Chinese (English) interchangeability, providing clear and intuitive images. Six temperature control values (set and actual values for column box, sampler, detector, etc.) can be displayed simultaneously on the same interface, with reserved areas for fault alarm location and time display
※ Easy to understand Chinese operation keyboard: It can intuitively set the temperature, time, range, stopwatch, temperature protection value, detector range, polarity, current and other parameters of the instrument. With one click operation, you can learn instrument operation in a short time (foolproof operation)
According to the different analysis and application needs of customers, FPD, NPD, and ECD detectors can be flexibly installed;
The main control circuit adopts a functional microprocessor, large capacity FLASH flash memory, and EEPROM memory
GC-7890 has a dual temperature protection device. Regardless of which temperature exceeds the set value, the instrument will stop heating and send an error message for use;
The temperature program has the ability to reach 8 levels and 9 platforms, and can be extended to 16 levels according to customer requirements to adapt to the analysis of complex samples with wide boiling ranges and low content;
GC-7890 provides multiple options for selecting injectors and detectors. Fill the column for injection, gas injection, and instantaneous vaporization injection; Capillary non split injection, capillary split/non split injection, direct injection into large-diameter columns; Clean the injector with a diaphragm, etc.
