3、 Main functions and features

1. Fully automatic system, safe and reliable, one click operation, can be unattended

2. Modular design of software and hardwareCompact structure

3. The large touch screen interface is rich in information, simple in human-computer interaction, easy to operate, and has the following functions:

a)LCD screenThe displayed information includes:Multi method parameter setting, real-time working status, running process and timeInformation, etc

b)Headspace vial, injection system, and sampling (injection) catheter,Unified coordination through touch screenThree way heating and temperature control

c)10 methods for editing, storing, and calling at any time

d) Can start synchronouslyGC、 Chromatographic data processing workstation, also available外部Event program starts this device, achieve multiple repeated injections of the same sample bottle

e)haveSelf checking function(Board level and gas circuit)And fault displayfunction

4. The sample tray is automatically positioned and the dial number is displayed in real-time on the screen

5. The sample transfer tube (including sampling needle) and injection valve have automatic blowback function, which avoids cross contamination of different samples

6. The combination of a six way valve and a quantitative loop effectively reduces dead volume and improves analytical sensitivity

7. The six way valve and transmission pipeline link have no transmission cold points, ensuring the integrity of the sample

8. Allow for secondary sample addition during the experimental process without the need for resetting or interrupting the original experimental sequence, flexible and convenient

9. Support sample bottle oscillation function, shorten balance time, improve sensitivity and repeatability
