45 bit fully automatic headspace sampler

1Characteristics and main functions of the instrument

1Power on self-test,different levelsFault alarm and prompt, automatic positioning of sample tray；

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

3Through time programming, automatic functions such as pressurization, sampling, injection, analysis, and post analysis blowback cleaning can be achieved；

4. Silanizationchemical inertnesstransformProcessing, sample flow pathandallAdopting constant temperature controlAfter each injection is completed, the system automatically uses inert gas for purgingsamplepipelineAnd quantitative loopTo prevent cross contamination；

5The heating position has oscillation function,Adjustable speed,Can reduce the time required for the sample to reach equilibrium;

6One click call to stored headspaceProgram, press the run button to automatically complete all sample analysis，Real time animation displaySample dynamics;

7The sample transfer tube and injection valve have automatic blowback function, which avoids cross contamination of different samples；

87-inch touch screen display, easy to operate，And display the dynamic flow path of the gas path in real-time through images；

9. Real time display of the number and location number of samples being heated in the heating position on the screen, as well as real-time display of the sample to be injected and the sample to be injected；

10. Using AFM technology, the carrier gas and pressurized gas can be digitally displayed with an accuracy of 0.01psi, ensuring consistent conditions for each headspace sampler and guaranteeing quantitative analysis results;

11The instrument is equipped with an electronic version for easy teaching, making it convenient for beginners to learn and use on the spot；

12. Compatible with various brands and models of GC both domestically and internationally, and can be connected in series；Not occupying the injection port, no need to remove the liquid automatic sampler; Parallel connection can also be used for convenienceComplete the replacement of different GCs within 30 seconds.
