ZY-3400NAutomatic TypeLow temperature concentration devicecorrectBeijing Zhongyi Yusheng Technology Co., Ltd. independently developed and specializes in《GB/T14678-93 Air quality - Determination of hydrogen sulfide, methyl mercaptan, methyl sulfide and dimethyl disulfide》And design,Equipped with automated design, touch screen display, and simple and convenient operation.
ZY-3400N automatic low-temperature concentration deviceCan be compatible with all imported and domestic productsGC、GCMSMatching.
2、 InstrumentCharacteristics and main functions
1. Power on self-test, fault alarm and prompt;
2. Color touch screen display, controlled by microcomputer program, with main functions including:
⑴ Method parameter setting, real-time display of working status, and running time;
⑵ The desorption zone, injection valve, and sample transfer tube are all separately heated and temperature controlled;
⑶ Set up the analysis program and press the run button to automatically complete the entire sample analysis;
⑷ The GC and chromatographic data processing workstations can be started synchronously, and the device can also be started by external programs;
3.useIndependent Research and DevelopmentelectronCold trap technology，Advanced bipolar four layer refrigeration chip, optimized structural design, effectively improves refrigeration capacity and rapid thermal desorption ability, greatly enhancing detection accuracy.
4. Through time programming, automatic functions such as sample adsorption, desorption, injection, and blowback cleaning can be achieved;
5. The sample transfer tube and injection valve have automatic blowback function, which avoids cross contamination of different samples;
6. In order to make it more convenient and accurate to use with imported gas chromatographs, this instrument is also equipped with dedicated interfaces for various imported instruments, which are easy to connect;
7.Equipped with an adjustable vacuum pump, the sampling flow rate is more stable;
8. The instrument gas pipeline and sample transfer pipeline have undergone inert treatment to ensure that the sample passes through without adsorption.
