GC9890EIntelligentgas chromatograph

The new sampler system has excellent data communication, analysis, and processing functions, and is easy to operate and learn.

The independently developed instrument control system, reliable anti-interference system, and optional automatic sampler enable unmanned gas chromatography analysis. Realize automation, intelligence, and diversification of operations.

The instrument can achieve 6-channel EPC control, and the EPC (Electronic Flow Control) system makes it easy to set the gas flow rate accurately, improving the reproducibility and stability of analysis and ensuring the authenticity of experimental results.

This instrument has a wider temperature control range: ambient temperature+5 ℃ -450 ℃ makes the analysis of samples more extensive.

The gas cut-off protection system can greatly prevent damage to the thermal conductivity detector and chromatographic column.

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

Intelligent gas chromatograph instrument parameters:

Temperature range: -80 ℃ (liquid nitrogen) -450 ℃

Program heating: heating rate 0-50 ℃/min; Incremental 0.1 ℃/min; Temperature control accuracy ± 0.015 ℃

Users can recalibrate the furnace temperature and set the protection temperature themselves.
