ATDS-20StypeDual channelFully automatic thermal desorption instrument(Once)

1Instrument Introduction

ATDS-20StypeDual channelThe fully automatic thermal desorption instrument isBeijing Zhongyi Yusheng Technology Co., Ltd. has developed and launched a dual function system with fully automated design, touch screen display, and more convenient operation for continuous operationA new generation fully automatic thermal desorption instrument with 20 samples.

ATDS-20S Dual Channel 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 300-2017 Determination of Toxic Substances in Workplace Air》

2、 InstrumentCharacteristics and main functions

1. It can automatically run 1-20 samples from both channels 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 Desorption zone, injection valve, sample transfer tube,variousEach road is individually 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;

8. In order to make it more convenient to use in conjunction with imported gas chromatographsaccurateIndeed, this instrument is also equipped with dedicated interfaces for various imported instruments, making it easy to connect;

9. For active substance analysis, an elastic quartz tube can be selected as the sample transfer tube;

10. The injection needle is easy to replace and can be connected to all models at home and abroadGC injection port.
