The capillary system has adjustable tail blowing, adjustable diaphragm cleaning, and adjustable flow ratio.
The new FID has high sensitivity and can be conveniently maintained for nozzles and ion collection electrodes.
It has six vertical temperature control zones, and each vaporization chamber, detector, and amplifier adopts modular design, with flexible and simple combination.
Large capacity chromatography column box, capable of simultaneously installing capillary and packed columns, with three vertical injectors. According to analysis requirements, gas and liquid injection ports can be installed, making it easy to install wide caliber capillary columns; According to the analysis requirements, it is also possible to add six way valve injection, conversion furnace device, etc., and achieve the series and parallel operation of detectors.
