Product Introduction

GC-6890 typeSpecialized universal gas chromatographIt is a cost-effective analytical instrument that is controlled by a microcomputer, operated by a keyboard, and displayed with a Chinese menu on a LCD screen. It has high electronic circuit integration, good reliability, simple operation, memorization of set parameters, no need to reset every time, and is suitable for long-term operation.
The combination of a large column box and a large fan with an automatic rear door cooling system has increased the cooling speed of the column box, truly achieving near room temperature operation. The instrument can flexibly use capillary columns, glass columns, and stainless steel columns. Can perform constant temperature and programmed heating operations.

Performance characteristics

※ Adopting a large screen LCD Chinese display. Easy to operate and learn

※ It has functions such as self diagnosis, over temperature power-off protection, file storage, calling, and five step program temperature rise, as well as single column automatic compensation function; Can ensure the stability of the baseline during program temperature analysis;

Equipped with six independent temperature control zones and an intelligent rear door opening system, the cooling speed is very fast; Each gasification chamber, detector, and amplifier adopts modular design, making installation and replacement very convenient;

Equipped with a separate and complete capillary analysis system, an independent capillary splitter injector (including diaphragm cleaning, splitting, and tail blowing adjustment). Optional capillary splitter/non splitter injector;

The instrument is equipped with five types of detectors: hydrogen flame detector, thermal conductivity detector, flame photometry detector, electron capture detector, and nitrogen phosphorus detector. Users can choose and select according to their own analysis requirements, or add six way valve injection, conversion furnace device, etc; And it can achieve the series and parallel operation of detectors.
