The inlet port adopts a new design, and the dual-column compensation function not only solves the baseline drift caused by programmed temperature rise but also reduces the influence of background noise to obtain a lower detection limit.
The compact design of the vapor chamber makes the volume smaller;
Replacement of accessories such as feed pads and nozzles can be done with one hand; the main parts, such as filled columns, TCD, FID detector, etc., can be disassembled entirely with only one plate hand, making maintenance very convenient.
Intelligent rear door opens to control the air volume of import and export, shortening the equilibrium time for system stability after programmed temperature rise/reduction.
Up to 4 types of injection ports can be installed: packed column, capillary column, and shunt/non-shunt injection systems are available.
The instrument has a 4.3-inch color LCD touchscreen and keyboard input for user-friendly operation.
Adopt primary pressure regulator valve and flow regulator/pressure regulator valve double stable gas circuit design.
Temperature control device to ensure that the temperature control accuracy is less than ± 0.1 ºC.
Double over-temperature protection and power failure protection function
Fault self-test and alarm function to ensure stable operation of the machine.
