Fully automatic headspace sampler (available in 10/20/30/40/60/80/120 positions for selection)

The main functions and characteristics of a gas chromatograph for residual solvents in food packaging are:

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

2. Modular design of software and hardware, compact structure;

3. The software interface is rich in information, simple in human-computer interaction, easy to operate, and has the following functions;

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

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

10Provide methods for editing, storing, and calling at any time;

Can start synchronouslyGCThe chromatographic data processing workstation can also be activated by external event programs to achieve multiple repeated injections of the same sample bottle;

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. Allow continuous addition of samples during the experimental process without the need to reset or interrupt the original experimental sequence, flexible and convenient;

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

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

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

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

10. Support the installation of sample bottle oscillation function, shorten balance time, improve sensitivity and repeatability (user selectable);

11. Can add heating position oscillation function;

12. Can increase multiple headspace concentrations（MHC）Mode, in one goGCDuring operation, it can execute up to100Secondary headspace;

13 GCThe software comes with a sequence injection setting, which facilitates the identification of samples and injection times;

14. Optional gas cut-off protection function, when the carrier gas pressure is lower than0.1MPaAt this time, the instrument automatically shuts down the main control circuit and enters standby mode to protect the detector and chromatographic column.

15. Support dual tower injection and simultaneous installation2individual24Automatic sampler, optional up to160The sample bottle workstation makes analysis simpler and more efficient.

16. Modular filling column injection port581Separate flow with capillary column/No diversion injection port671All adopt the glass lining tube mode, which is easy and convenient to maintain.

17. Gas path pressure and flow control and display mode: manual adjustment of electronic display or electronic gas path automatic controlEPCThere are two modes to choose from.

18All detectors and injection ports use high-precision electronic gas paths with temperature compensationAPC/AFCController, which can set the gas flow rate, purge flow rate, and split ratio of the chromatographic column in the display screen and software. It can also set the flow rates of hydrogen, air, and tail gas, making it easy and efficient to operate;

iCan be installed at most6Block Three RoadAPC/AFCModules, total18roadEPCCustomize the control air path.

19. Electronic pressure display mode（G60E）Maximum number of measurement channels6Road or9Road; range0～0.3Kpaor0～0.6Kpa

20. Support custom mode for temperature control zone names, making it convenient for users to remember and operate.

21. Data can be accessedDCSThe system completes the statistics, analysis, and monitoring of chromatographic component content, improving the automation level of production process control.

22. Support3individualIPThe address accesses the chromatograph host at the same time, and can be connected to the local processing (laboratory technician), unit supervisor (team leader), and superior supervisor (special supervisor, chief engineer, etc.) through the Internet, which can facilitate multiple people to monitor the operation of the instrument and analyze data results in real time, and improve the cooperation and timeliness of work.

23. Equipped with a networked chromatography workstation, a computer can monitor simultaneouslyNThe gas chromatograph can support multiple chromatographs to simultaneously process and control data, effectively solving the problem of too many laboratory computers and freeing up experimental space.

24. The analysis results can be optionally uploaded to the laboratory information management system（LIMSThe system facilitates the collection, analysis, reporting, and management of laboratory data and information.
