ATDS-20AType fully automatic thermal desorption instrument（once）
1Instrument Introduction
ATDS-20AThe fully automatic thermal desorption instrument isBeijing Zhongyi Yusheng Technology Co., Ltd. has developed and launched a fully automated design, touch screen display, more convenient operation, and continuous operationA new generation fully automatic thermal desorption instrument with 20 samples.
ATDS-20A Fully Automatic Thermal Desorption InstrumentCan be used with all imported and domestic gas chromatographs, cansatisfyThe following standards:
1.《HJ/583-2010 Determination of Benzene Compounds in Environmental Air Solid Adsorption/Thermal Desorption Gas Chromatography;
2.《GB/50325-202Indoor environmental pollution control in civil construction projectsstandard》；
3.《GBZ/T 300-2017Occupational Health 》
2、 InstrumentCharacteristics and main functions
1. It can automatically run 1-20 samples without the need for personnel on duty;
2. Power on self-test, fault alarm and prompt, automatic positioning and calibration of sample disk;
3. Microcomputer program control, with main functions including:
⑴ Method parameter setting, real-time animation 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 analysis of all samples;
⑷Normal temperature secondary desorption components or low-temperature secondary desorption components can be added according to user needs；
⑸ The GC and chromatographic data processing workstations can be started synchronously, and the device can also be started using external programs;
4. The machine comes with the function of simulating and sampling standard samples, which makes it more convenient to create working curves through a thermal desorption instrument;
5. The built-in sampling tube activation program can be loaded to automatically activate the desorbed sampling tube;
6. Through time programming, automatic functions such as desorption, injection, and blowback cleaning can be achieved;
7. The sample transfer tube and injection valve have automatic blowback function, which avoids cross contamination of different samples;
In order to provide more convenient and accurate use for imported GC and GCMS, this instrument is also equipped with dedicated interfaces for various imported instruments,Can connect all models both domestically and internationallyGC、GCMS；
9. For active substance analysis, an elastic quartz tube can be selected as the sample transfer tube;
