Main Technical Performance
-
High performance column box
The temperature control range of the column box is wide. High temperature control accuracy ensures high reproducibility of analysis;
The large volume structure ensures convenient installation of various specifications of packed columns and capillary columns for users;
The automatic rear opening of the column box can accelerate the cooling of the furnace temperature and automatically adjust the amount of cold air intake, which is more suitable for capillary chromatography analysis.
|
Multiple configurations of injection system
◎ Various diameters of packed columns can be configured for vaporization injection or column loading, capillary split or non split injection, gas valve injection, etc.:
The packed column and capillary column can be installed simultaneously, making it easy to change the separation method according to analysis requirements. Diversify the analysis.
A wide variety of detectors
All detectors adopt a modular design. It has the characteristics of high sensitivity, low noise, and wide linearity.
◎ Multiple detectors can be configured, including TCD, FID, ECD, FPD, NPD, etc., and can also be used to detect elm species simultaneously
