GC9890E Type Gas Chromatograph

New sampling system with excellent data communication, analysis, and processing capabilities, easy to operate and learn.

Self-developed instrument control system, reliable anti-interference system, optional automated sampler, achieving unmanned gas chromatography analysis. Achieves operation automation, intelligence, and diversity.

The instrument features 6-way EPC control, with the EPC (Electronic Flow Control) system allowing for clear visibility of individual flow rates, facilitating precise gas flow setting. This enhances the reproducibility and stability of the analysis, ensuring the authenticity of experimental results.

The instrument features a broader temperature control range: ambient temperature +5℃ to 450℃, enabling a wider variety of analysis samples.

Gas Cut-off Protection System, which can greatly prevent damage to the thermal conductivity detector and chromatography column.

This instrument can be equipped with a low-temperature control system, achieving temperature control down to -80°C, which is sufficient to meet your needs for analyzing low-boiling point substances.

Intelligent Gas Chromatography Instrument Parameters:

Temperature Range: -80℃ (Liquid Nitrogen) - 450℃

Programmed Temperature Rise: Heating Rate 0-50℃/min; Increment 0.1℃/min; Temperature Control Accuracy ±0.015℃

Users can recalibrate the furnace temperature and set the protective temperature.
