TD-3400TVOC thermal analyzer

TVOC 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.

Usage and application scope:

The thermal desorption instrument can be used with all imported and domestic gas chromatographs, and the detection concentration of volatile organic compounds in the environment can reach ppb level. In addition to meeting the requirements of "Determination of Benzene in Indoor Air" and "Determination of Total Volatile Organic Compounds (TVOC) in Indoor Air" in GB50325-2010 "Code for Indoor Environmental Pollution Control of Civil Building Engineering", the multifunctional thermal desorption instrument can also be applied to the following fields:

1. Occupational safety, industrial hygiene, and environmental monitoring;

2. Rapid identification of unknown atmosphere;

3. Analysis of spices and essence;

4. Assessment of toxic substance accidents (when personnel can safely return to the accident site);

5. Perimeter environmental safety monitoring of chemical weapons warehouses;

6. Quality control testing in polymer and packaging industries;

7. Evaluation of drug solvents and product purity;

8. Residual analysis of drugs and court samples;

9. Collect exhaled gases from patients and detect volatile drug metabolites in their blood in hospitals.

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;
