Chromatographic injection thermal analyzer

Chromatographic injection thermal analyzerIntroduction to the device:

Thermal desorption instrument is a new type of sample pretreatment device that integrates thermal desorption, simulated sampling of standard samples, and activation design of desorption tubes, making it economical and practical.

Features and main functions:

• Integrated design of thermal desorption instrument, simulated sampling, and adsorption tube activation instrument, more practical and convenient;
• Automated design, versatile and easy to operate;
• 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;
• Equipped with an external carrier gas regulation system, it can be connected and used without any modifications to the GC, and the original instrument carrier gas can also be used;
• Desorption injection analysis and activation adsorption tube can be performed simultaneously without affecting each other;
• The sample transfer tube and injection valve have automatic blowback function, which avoids cross contamination of different samples;
• Through foreign affairs time programming, automatic functions such as desorption, injection, analysis, and post analysis blowback can be achieved;
• For active substance analysis, an elastic quartz tube can be selected as the sample transfer tube;
• In order to make it more convenient and accurate to use with imported gas chromatographs, this instrument is also equipped with interfaces for various imported instruments, which are easy to connect;
• The injection needle is easy to replace and can be connected to all models of GC injection ports at home and abroad.
• Microcomputer control, large screen LCD display, touch keyboard, numerical input, main functions include:

⑴ Method parameter settings, real-time working status, and running time;

⑵ The desorption furnace, activation furnace, injection valve, and sample transfer tube are all independently heated and temperature controlled;

⑶ Set program control, press the run button to automatically complete the entire sample analysis;

⑷ It can store 9 methods for easy calling at any time, achieving fast startup and analysis;

⑸ The GC and chromatographic data processing workstations can be started synchronously, and the device can also be started using external programs;

Main technical parameters:
