6Wide temperature control range: ambient temperature+5 ℃~450 ℃, making the sample analysis range wider.
7Can be installed with the American HP-5890 gas chromatograph micro thermal conductivity detector to achieve complete docking.
8The unique gas cut-off protection system can minimize damage to the detector and chromatographic column.
9The column box can be equipped with an ultra-low temperature control system, with an ultra-low temperature control of -80 ℃, to meet your needs for low boiling point substance analysis.
10. The inter column compensation circuit electronically compensates for baseline drift during program temperature rise, reducing the complexity caused by the second column, detector, and auxiliary flow system. Two single column compensation channels can be installed simultaneously.
Column temperature box system
Temperature range: ambient temperature+5 ℃~450 ℃
Third order programmed heating, with a heating rate of 0-50 ℃/min; Incremental 0.1 ℃/min. Temperature control accuracy ± 0.015 ℃,
Users can recalibrate the furnace temperature and freely set the * temperature. The intelligent rear door opening system has stepless variable air flow in and out, which shortens the stable balance time of the system after heating/cooling. The time taken for the column box to drop from 350 ℃ to 50 ℃ is less than 6 minutes.
