Fully automatic headspace gas chromatographMain functions and features:

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

2. Modular design of software and hardware, compact structure

3. The software interface is rich in information, with simple human-computer interaction and easy operation. It has the following functions:

a) Display information includes: multi method parameter settings, real-time working status, running process and time information, etc

b) The headspace bottle, injection system, and sampling (injection) catheter are coordinated through software to achieve three-way heating and temperature control

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

d) The GC and chromatographic data processing workstations can be synchronously started, and the device can also be started using external event programs to achieve multiple repeated injections of the same sample bottle

e) Equipped with self checking function (board level and gas circuit) and fault display function

4. Automatic positioning of the sample disk and real-time display of the disk number on the software end

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 ring 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. Support dual channel injection function for the same sample (user selectable)

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