Power on self-test, fault alarm and prompt, automatic positioning of sample tray;

Microcomputer program control, main functions include:

(1) Method parameter setting, real-time animation display of working status, and running time;

(2) The sample area, injection valve, and sample transfer tube are all individually heated and temperature controlled;

(3) Set up the analysis program and press the run button to automatically complete the entire sample analysis;

(4) It has multiple expansion functions: dynamic headspace, purge and capture, low-temperature cold trap;

(5) The GC and chromatographic data processing workstations can be started synchronously, and the device can also be started using external programs.

Equipped with an external carrier gas regulation system, headspace injection analysis can be performed without any modifications or changes to the GC instrument. The original instrument carrier gas can also be used.

Through time programming, automatic functions such as pressurization, sampling, injection, analysis, and post analysis blowback cleaning are achieved. Pressure balanced injection technology is used for headspace sampling with narrow peak shape and good repeatability.

The sample transfer tube and injection valve have automatic blowback function, which avoids cross contamination of different samples.

For active substance analysis, an elastic quartz tube can be selected as the sample transfer tube.

The injection volume can be adjusted according to the concentration of the sample to be analyzed by the customer.

The injection needle is easy to replace and can be connected to all models of GC injection ports at home and abroad.
