Fully automatic headspace sampler-Suitable for different sample matrices - high-precision dynamic/static analysis - reliable results and reproducibility

AHS-900AtypeFully automatic headspace samplercorrectOur company has independently developed a multi station high-precision fully automatic headspace sampling system. The system performs self inspection and fault alarm upon startup, and can be loaded at full load once20Head space bottle, compatible with all domestic and imported productsGC、GCMSOnline.

By combining electric six way valves and solenoid valves, high-precision quantitative ring sampling with inert treatment is widely used for residual ethylene oxide in pharmaceuticals6Residual solvents, analysis of benzene derivatives, detection of alcohol in blood, analysis of drinking water and tap water.

3. Mobile phone connection, remote control (can be monitored, operated, optional);

4Intelligent color touch screen, easy to set and operate, clear at a glance;

5. Power on self-test and fault alarm function;

6. Standard configuration20Position, quiet/Dynamic optional;

7. Applicable10ml、20mlHeadspace bottle, meeting a large number of analytical requirements;

8. Comprehensive dynamic headspace components to improve sample analysis sensitivity;

9. The starting and ending bottle positions can be freely set to meet special on-site requirements;

10. The reliability of valve and quantitative loop technology is very high in use, and the analysis results have high reproducibility;

11. All sample flow paths have undergone insulation treatment and chemical inertness treatment, which greatly reduces analytical residues and maintains the integrity of the sample;

12. Synchronously start gas chromatography-Mass spectrometry, data processing workstations, and external event programs can also be used to start this device, achieving communication and dialogue between pre-processing equipment and analytical instruments to avoid wasting analytical samples caused by instrument failures (prior communication is required);

13. Universal interface, compatible with any brand of gas chromatographGCandGCMSJoint use, universal synchronous control docking method;
