Product Model:ATDS-7890 Intelligent Thermal Analyzer

1、 Instrument Introduction

This instrument is suitable for measuring the boiling points of chemical building materials, food, atmosphere, and indoor environments350Qualitative and quantitative detection of various gases below ℃,canandAny domestic、countryExternal gas chromatographyceremony、GC-MS (Gas Chromatography-Mass Spectrometer)Connected, its automation level, repeatability, sensitivity and other indicators can fully meet the newly issued national standards for environmental testing, and it has its own unique functional advantages and satisfactory performance price ratio in terms of structure.Fully automated design, touch screen display, and more convenient operation.

IIInstrument features and main functions

1、All sample transmission pipelines adopt imported high inertia deactivation pipelines, with no residue or cross contamination, ensuring the repeatability and accuracy of sample injection；

2、 Microcomputer program control, main functions include:

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 heated and temperature controlled separately;

⑶ Set up the analysis program and press the run button to automatically complete the sample analysis;

⑷ It can be configured as a room temperature secondary desorption instrument or a low-temperature secondary desorption instrument according to user needs;

⑸ Can start synchronouslyGCThe chromatographic data processing workstation can also be started with external programs;

4The 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、Adopting a high-temperature six way valve, the operating temperature can reach240℃；

6Through time programming, automatic functions such as desorption, injection, and blowback cleaning can be achieved;

7The sample transfer tube and injection valve have automatic blowback function, which avoids cross contamination of different samples;

8In 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;

9、The connection point between the six way valve and the transmission pipeline is located inside the heating insulation box, without any transmission cold points, ensuring the integrity of the sample；

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

11、Integrated design, compact overall structure; Microcomputer control, all in Chinese7inchLCD display, easy and convenient to operate.
