From the content of organic compounds such as air, water and soil to the detection and analysis of crops, beverages, desserts and other foods, the secondary thermal analyzer is used in various research institutes, laboratories, food and drug safety testing departments, factory quality control workshops, etc. Next, let us understand the characteristics of the secondary thermal analyzer as a widely used detection and analysis instrument.

1. Integrate injection analysis. When the secondary thermal analyzer is working, it can be directly sampled through the adsorption tube and can be directly connected with chromatographs of different brands.

2. Strong function.secondary thermal analysisThe instrument adopts an integrated control system with multiple functions, high practicability, small size and large scalability.

3. Stable airflow. The secondary thermal analyzer adopts a high-precision regulator valve, which has high pressure stabilization accuracy and stable airflow.

4. volatile small. The gas path pipe of the secondary thermal analyzer is generally passivated and polished 316 or imported high inert and deactivated stainless steel. The sealing material is mainly used silicone rubber sealing ring and PTFE material. Therefore, the volatility of the test sample at high temperature is very small.

5. High temperature resistance. The heating valve box adopts precision high temperature resistant six-way valve, no dead volume, the use temperature can reach 200 ℃.

7. Integrated design. The integrated design of the heating valve box and the heating gas circuit of the secondary thermal analyzer effectively reduces the intermediate links and alleviates the problem of low analysis rate caused by dead volume to a certain extent.

8. Small size. By calculating the diameter of the analysis tube and the gas path, the dead volume of the connection point of the analysis tube and the gas path is reduced to a lower level, thereby improving the detection quality.

Generally speaking,secondary thermal analysisThe instrument has the characteristics of sample collection, strong function, stable performance, low volatility, high temperature resistance, heating valve box, gas path integrated design, small dead volume and so on. Compared with the traditional primary thermal analyzer, these characteristics make the secondary thermal analyzer have great advantages, and it is very useful in the detection accuracy and accuracy, especially the air detection containing benzene or benzene.
