Gas chromatograph

brief introduction：

The GC-9870 high-end gas chromatograph is an upgraded product based on our company's GC-9860. It has a stylish appearance and a reasonable structure design, and is equipped with our independently developed Chinese and English display technology. The automation level and overall performance have been greatly improved. The highly stable and sensitive microcurrent amplification technology significantly increases the detection limit of FID, and the sensitivity of the new thermal conductivity detector is increased by 5 times. Shortening the gap between domestic and imported models can meet the needs of petroleum, chemical, pharmaceutical, food, environmental protection, disease control, scientific research institutions, and quality inspection departments.

Main technical indicators：

Switching display technology between Chinese and English, with a 5.7-inch LCD screen (320 * 240). Up to 20 display interfaces, rich in information, can store 20 sets of chromatographic analysis data, and can be called up at any time.

Industrial design appearance, novel and elegant, beautiful and practical, reasonable structure, and comfortable operation.

Gas interruption protection function, protecting chromatography columns, thermal conductivity cells, electron capture detectors, etc.

The eighth order linear programming heating function and intelligent dual rear door design truly achieve near room temperature control, with a temperature control accuracy of ± 0.1 ℃ to meet the requirements of wide range analysis.

Complete over temperature thermal protection and platinum resistance open circuit and short circuit alarm functions ensure that the instrument is not damaged.

● Self diagnostic function and Chinese fault prompts, making it convenient for users to know the cause and location of the problem.

Adopting advanced FLASH memory system, data protection no longer relies on batteries.

The microcomputer controlled FID detector has achieved automatic ignition function.

The high-precision stable voltage and flow mode ensures precise and stable airflow, achieving a multi-channel air path control system.

A high-performance capillary vaporization chamber achieves a true split/no split injection system.

Can install 1-4 detectors simultaneously. It can operate with dual FID or dual TCD, dual ECD or dual NPD. TCD is equipped with dual column post supply gas, so it can be used with single column, dual column, or capillary column.

Can install and run 1-3 sets of capillary columns simultaneously, and can run 3 detectors simultaneously. One instrument is equivalent to three (shared in the column room). Or dual FID dual hair. Double TCD double hair. Dual TCDs work simultaneously without affecting each other, and the carrier gas can be independent of each other. Avoiding the tedious process of replacing chromatography columns and detectors.

It can achieve the serial and parallel use of detectors, and intelligent automatic conversion can be achieved through event control.

The instrument can be equipped with various injection methods such as conversion furnace, thermal desorption instrument, automatic sampler, automatic headspace sampler, and cracking device. Can be timed for automatic sampling, achieving automatic online analysis.

The instrument is particularly suitable for various enterprises, technical supervision bureaus, environmental monitoring, health and epidemic prevention, universities, scientific research and other departments.

Equipped with various detectors such as FID, TCD, ECD, FPD, etc.
