IIInstrument features and main functions

1. Equipped with leak detection function, a tightness test must be conducted before each program run to ensure that the sample is not lost during analysis and to guarantee the recovery rate;

2. Equipped with dry blowing function, the sampling tube is automatically dried and removed during each analysisAnalysis tubeOxygen and water vapor in the middle to ensure peak effect and avoid separationDamage caused by analytical instruments (especiallyGC-MSFilament);

3Analysis tubeHeating、pipeline、Six way valve, etcThe heating temperature can be independently set；The sample flow path must be an inert pipeline that has undergone silane treatment to avoid residuemakeCross contamination；

4. Equipped with aging function, it automatically analyzes after each analysisAnalysis tubeAging is carried out to ensure that there is no residue in the sample tube after each analysis, and it can be directly sampled outside;

5Using touch screen editing, saving, and calling methodsIt can automatically save multiple experimental methods, making it more convenient to use.

6. Through time programming, it is possible toDynamic implementationDry blowingDesorption, injection, blowback、wash（activation）Other functions;

7. Adopting semiconductor refrigeration, high cooling efficiency, no need for external refrigeration devices, saving usage costs;

8The cold trap focusing tube adopts ultra-low adsorption quartz tube with the smallest inner diameter≤ 0.9mm (in accordance with HJ644 requirements);

9adoptSimplee-LocK Locksealtechnical implementationAnalysis tubesimple and convenientreliableFixed and sealed,Completed in 2 secondsAnalysis tubeThe fixation and disassembly achieve efficient work efficiency;

10Equipped with analog sampling device as standard,It can be more conveniently achieved through pyrolysisanalyzeInstrument production work curve；

11、Can work with any brand both domestically and internationallyThe combination of GC/GC-MS can be used in series without occupying the injection port, or in parallel with the analytical instrument that can be replaced in just a few seconds; You can freely choose according to the usage environment.
