GC-9870Type * * gas chromatograph is used in our companyGC-9860On the basis of this, we have upgraded and replaced our products with a stylish and structurally sound design, while also incorporating our company's independently developed display technology in both Chinese and English. This has significantly improved its automation level and overall performance. The highly stable and sensitive microcurrent amplification technology enablesFIDThe detection limit has been significantly improved, and the sensitivity of the new thermal conductivity detector has been enhanced5Twice. Shortening the gap between domestic and imported models, it can meet the needs of petroleum, chemical, pharmaceutical, food, environmental protection, disease control, scientific research institutions, and quality inspection departments.

1、 Main technical indicators:

Switching display technology between Chinese and English,5.7Inch LCD large screen（320*240）. up to20A display interface with abundant information and storage capability20Set chromatographic analysis data and can be accessed at any time.

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

● Gas cut-off protection function, * * limited protection for chromatographic columns, thermal conductivity cells, electron capture detectors, etc.

● Eight order linear program heating function and intelligent dual rear door design, * * achieving near room temperature control with high temperature control accuracy of ±0.1℃ meets the requirements for wide range analysis.

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

● Self diagnostic function and Chinese prompts for faults, allowing users to easily understand the cause and location of the problem.

● Adopting advanced technologyFLASHMemory system enables data protection to no longer rely on batteries.

● Microcomputer controlFIDThe detector has achieved automatic ignition function.

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

High performance capillary vaporization chamber achieves * * flow separation in the sense of * */Non split injection system.

● Can be installed simultaneously1-4A detector. Can be doubleFIDOr doubleTCDOr doubleECDOr doubleNPDfunction.TCDEquipped with dual columns for gas replenishment, it can be used for single column, dual column, or capillary column.

● Can be installed and operated simultaneously1-3Install capillary column and operate simultaneously3A detector.1The instrument is equivalent to3Platform (shared by pillar room). Or doubleFIDDouble hair. twoTCDDouble hair. twoTCDWorking simultaneously without affecting each other, the carrier gases can be independent of each other. Avoiding the tedious process of replacing chromatography columns and detectors.

● It can realize the series and parallel use of detectors, and perform intelligent automatic conversion through event control.

The instrument can be installed with various injection methods such as conversion furnace, thermal desorption analyzer, automatic sampler, automatic headspace sampler, and disruptor. Automatic sampling can be scheduled to achieve 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.
