• Standard 30-position sample tray;
• Sampling dual triaxial motion platform, bottle taking and needle inserting are independent of each other, which improves the sampling speed, and at the same time improves the expansion ability of bottle position and furnace position;
• 8-position heating furnace can realize overlapping heating of multiple samples and reduce waiting time;
• The heating position has oscillation function (optional without oscillation), which can reduce the time required for the sample to reach equilibrium and improve the sampling efficiency;
• Needle heating function to avoid sample condensation and increase the accuracy of the experiment;
• The PC-side control interface can form a queue by discontinuously selecting multiple sample bits, which can realize the jump combination. At the same time, the priority order of the sample queue can be adjusted for the analysis of emergency samples;
• The same sample can be injected and analyzed many times, which can be used for the expansion and research of methods;
• The functions of self-check, fault alarm and prompt, temperature overload protection and leakage protection of the startup system increase the safety factor of the instrument;
• The sample transmission pipeline and injection needle are made of inert materials to prevent sample residue and loss;
• Gas path and sample bottle leak detection function;
• PC-side control, instrument operation dynamic diagram, comprehensive and intuitive, can grasp the instrument operation and the current state of each sample in real time;
• The GC and chromatographic data processing workstation can be started synchronously, and the reverse control with GC can also be realized. For the interfaces of various imported instruments, GC and GCMS at home and abroad can be connected.
• The sampling system has the function of automatic blowback, which can effectively reduce the cross-contamination of different samples;
• Optional electronic pressure control (EPC) system can reduce manual error and improve the accuracy and reproducibility of analysis;
• With the log function, you can view the operation records.
