Product Name:HS-12Type automatic headspace sampler

HS-12 automatic headspace sampleradopt7-inch touch screen with intuitive display,It has unique technical characteristics such as good universality, simple operation, and good reproducibility of analysis results. With a durable structure and simplified design, it is almost suitable for continuous operation in any environment.

Characteristics and main functions of the instrument

1. Suitable interface for any gas chromatograph,The injection needle is easy to replace and can be connected to all models at home and abroadGC injection port，Achieved maximum flexibility;

2. Narrow peak shape and good repeatability in headspace injection，Using valve and quantitative ring injection technology, fixed volume and known volume samples, precise temperature control ensures good reproducibility;

3. Needle heating function to avoid sample condensation and increase experimental accuracy;

4.7-inch touch screen, microcomputer control, LCD display, more convenient operation;

5. LCD screen display, comprehensive and intuitive: real-time working status, method parameter settings, operation countdown, etc; Real time monitoring of instrument operation and current status of each sample

6.3 Road Incident,Programmable auto run, storable100 methods that can be called at any time, achieving fast startup and analysis；

7.Can start synchronouslyGC、 The chromatographic data processing workstation can also be started with external programs to activate this device；

8. Heating and temperature control of metal bodies, with high temperature control accuracy and small gradient;

9.12 heating furnaces can achieve overlapping heating of multiple samples, reducing waiting time;

10. Three independent heating and temperature control systems for sample bottles, six way valve injection systems, and transmission lines;

11. Equipped with an external carrier gas regulation system, the GC instrument can be used for headspace sampling analysis without any modifications or changes, and the original instrument carrier gas can also be used;

12. The sample transfer tube and injection valve have automatic blowback function, which automatically cleans after injection to avoid cross contamination of different samples;

13. The self checking, fault alarm and prompt functions of the startup system, temperature overload protection function, leakage protection function, etc. have increased the safety factor of instrument use.
